Goals scored by Shamrock Rovers last weekend came from missed tackles or losing possession in midfield. “It was small individual battles that cost us the game and they may have come from inexperience.

“One thing you can’t give players is determination or will. They have to have that themselves. There were a few incidents in the game where we lost a tackle and ended up conceding a goal.

“We were also able to show the players that when we won the tackle what the difference was. Our goal was probably the best of the game. It came originally from Roberto [Lopes] winning the ball in a tackle.

“The good thing about it is we’re creating chances and we did it against one of the teams that’s going for the title. Overall, I thought there wasn’t a big gap between the two teams, despite the scoreline.”

Heary still has to plan without Anto Murphy (hamstring) and Dave Mulcahy (calf) who have proven ability to help control the midfield and defence.

Murphy’s injury has proven more serious than was thought at first and he may be out for a further three weeks. But Mulcahy, who has had a knee and a calf injury in quick succession, may be just a week from returning.

The presence of players like these can have a crucial effect on how the team plays. “It’s how they lead by example and how they talk to people. The midfield is crucial and if you have someone there who can see the danger before it happens it makes a big difference. Maybe last week we were just lacking that bit of experience.”

But Heary wants to ensure his players do not focus too much on whether a certain player is available or not, and he wants to encourage younger players to show leadership.

Craig Walsh (22) has demonstrated that ability. “He has a great engine. He’s up and down, working very hard,” said Heary. “The lads can’t go into games thinking, ‘We’re missing such a player, or such a player’. They have to think, ‘OK, let’s go and win the game without them’.”

Dundalk represent formidable opposition, Heary notes, with a squad that is relatively settled over a couple of seasons and “hard to find weaknesses in”. Though they lost heavily in the opening league game of the season, they have beaten Sligo away and defeated Shamrock Rovers in the Setanta Sports Cup.

Heary notes this inconsistency is widespread. “Everybody has already lost at least one game in the league, and that may be down to worrying too much about getting points.” But the Bohemian manager also expects some teams to start putting winning sequences together and his team may well have that opportunity after this weekend when they play Bray, Athlone and Limerick over eight days.

Apart from injuries to Murphy and Mulcahy, Bohemians also have Andy Mulligan (quad) out, though he has returned to light training.

Since then, Bohs have won three and drawn two of the last five league games between the two great clubs. Heary doesn’t necessarily believe that run has to end this week.

“I know some people have been saying ‘we haven’t lost to them in a while, we’re due to be beaten by them’, but I don’t understand that – why are we due to be beaten? We’ll push for the three points – we’ve done that in every game so far and tomorrow will be no different.”

Although the teams know each other well, Heary has made sure his players are well informed about Trevor Croly’s new-look team. “We don’t leave anything to chance, we try to give the players as much information as we can about how they play. The thing about Rovers is they have a wide selection of players. If you take their B team into account, they have up to 40 players to choose from, so it’ll be difficult.”

The atmosphere in the lead up to a Bohs-Rovers clash – and especially on the night – is unrivalled in League of Ireland football. Heary says his players are well aware of the importance of the game to the fans and hopes that can be to Bohs’ advantage. “There’s more expectation – the players know that. When they sign here, they know that these are the games that the fans love.

“With us and Rovers, that intensity is always there – no matter where either team is in the table – whether we’re fighting for leagues, cups or anything. I don’t think tomorrow will be any different. Hopefully we can adapt to that and get a result.”

The Bohs boss has been impressed with the attacking threat posed by his side – who have scored 13 goals in their four competitive games to date. “This year we’ve had the lads from pre-season, and we’ve worked a lot on their confidence – we wanted them to go out and express themselves. You can see that now with Dinny (Corcoran) whose confidence is high, Jay Byrne is chipping in, Paddy Kavanagh, Steven Beattie. We’ve plenty of attacking options and I think that gives the team that little bit of momentum.”

Captain Dave Mulcahy (knee) looks certain to miss out alongside Andy Mulligan (quad), and Lee Whelan (ankle). Anto Murphy is (hamstring) is still doubtful, while Karl Moore is available again following a groin injury.

“I suppose you might say we have a selection headache, but on the plus side we know that any player we choose is well capable of doing the same thing we’re doing, week-in and week-out,” he said.

Friday’s game brings together two teams with 100 per cent records in competitive football in 2014, and two managers who are at early stages in their careers. Heary and his Drogheda counterpart Robbie Horgan are classmates on the current FAI Pro Licence course.

“There’ll be bragging rights to play for,” commented Heary, who underlined his respect for what Horgan has achieved so far with victories over Dundalk in the Louth Cup and in the league.

“The two lads up front, Gary O’Neill and Fabio O’Brien, are a big threat,” said Heary, adding his admiration for O’Neill on his recovery from serious illness. “He’s a positive fellow and that stood to him.”

Heary is hoping Friday’s opponents might be “a bit leggy”, having played 120 minutes in the EA Sports Cup against Crumlin United on Monday. “But they’re a well-organised side and they have a big back four. We know it’s going to be a physical game,” he said.

The Bohemian manager insists that his team’s approach to Friday’s game will be similar to that adopted against Bray and UCD. “We don’t want the players going into this thinking at all negatively. We want them to be just as positive as against Bray and UCD,” he said.

“It’s our first home game and we want to give a good account of ourselves and get the crowd behind us. If the performance matches what we’ve done over the last couple of weeks, the people will keep coming and they’ll enjoy the matches.

“Drogheda winning last week is a good incentive to us to go at them, and take the game to them. We’ve shown we can limit our opponents’ scoring chances, and we are creating chances ourselves. We’re getting into the box, we’re getting crosses in, we’re getting goals and we aim to continue that.”

Jason Byrne came off the bench last Friday and scored within minutes for his second late goal in two games. He started Monday’s game and again scored, making it three goals in three games. According to his manager, he is “still getting his fitness levels up and getting his touch in, but he is a lot fitter than last year and the hunger’s still there”.

Defender Anto Murphy (hamstring) has returned to training but will not be ready for selection. Karl Moore (groin), Andy Mulligan (quad) and Lee Whelan (ankle) are out, while captain Dave Mulcahy (knee) faces a late fitness test.

But Heary has hinted that he could ring the changes and give others a chance to stake their claim ahead of Friday’s home league clash against Drogheda United, saying: “We’ve a talented squad here this season. I could make eight or nine changes and no matter who we bring in, they’ll be good enough and will give it their all for the jersey.”

After such a comprehensive victory against the Students just three days ago, the Gypsies could be forgiven for taking their foot off the gas tonight. But Heary doesn’t anticipate any such issue and said: “There won’t be any problem with motivation.

“The lads don’t need me to fire them up for a game like this – it’s a cup game, they all know they have to win it if they want to get closer to winning some silverware.”

The confident attacking style of play and quality of the goals scored on Friday earned his side great plaudits, but Heary is quick to praise the performances further back the pitch.

He said: “The goals were fantastic. Paddy’s was a cracker, Dinny’s was too and Jay’s only on the pitch a few minutes before getting on the scoresheet. But one of the most pleasing aspects for me was the clean sheet. The whole back five were fantastic.

“We were unlucky not to keep a clean sheet against Bray too. But for a penalty, we would have. We have to be strong at the back, so I’m delighted with how they’ve done so far.”
