The visitors expect Giovanni Trapattoni's side to adopt different tactics for Friday's game then those used in the goalless stalemate in Stockholm, leading to an open encounter
With the sides locked horns on eleven points alongside Austria, the clash represents a must-win game for both and Hamren is confident his side can come away from the Irish capital with the victory but insists they won't underestimate their inferiorly ranked opposition.
"I expect a different kind of match to the one in Stockholm, a more open game. I hope we’ll be able to find the space in behind them to play the ball into." Hamren said in the pre-game press conference.
"They (Ireland) will hopefully open up a little more, opening up space for us, but then that means we’ll have it a little more difficult defensively.
"Underestimating? You can forget that. That never happens at this level. Maybe in a friendly, but not in a competitive game."
"If we play as we should and we have trained, we want to keep the distance between the parts of the team the same wherever we are on the pitch, whether we press high or not."
"We don’t want them coming at our central defenders facing the right way with the ball. Every team wants to get the ball into that area." he added.
The Scandanavians don't have happy memories of Dublin, having not won there since 1949 while their last trip to Lansdowne Road resulted in a 3-0 defeat but Hamren has downplayed his sides' poor record against the Boys in Green.
"My hope is that it is of less importance whether one plays at home or away, because that means you have a good team." The 56-year-old tactician explained.
"We had two defeats in the Euro qualifiers, both away, and we’ve had one in the World Cup qualifiers, also away."
"The bigger and better the performance the more likely you are to win . and if we can’t do that we’ll have to try to battle our way to it."
"We always have the ambition of playing well but it doesn’t always work out that way. Sometimes we’ve had to fight and we’ve won a few games that way. We have a plan, we have possibilities through substitutions and changes on the field."
The Sweden boss will have to do without towering centre-back Andreas Granqvist through suspension, with Adam Johansson set to deputise for the former Wigan man, but Fulham's Alex Kacaniklic has recovered from injury and will provide some much needed attacking flair.
Sunderland winger Sebastian Larrson had no hesitation in claiming the visitors had a better side on paper but has warned his teammates not to take anything for granted.
"Obviously I think we have a better team, but I don’t underestimate Ireland at all. I think and believe that we are good enough to take ourselves to the World Cup." He said.
"Ireland have a good team that have players playing in the top leagues. I’m convinced that we will succeed, both the players and I believe that."
Meanwhile, the 28-year-old set-piece specialist has identified James McClean, his former team-mate at the Stadium of Light, as a threat to the Swedish defence when the two sides clash on Friday. The Derry-born winger excelled on the left-side of midfield in Stockholm and has been handed that role once again by Giovanni Trapattoni, with Larsson quick to acknowledge the match-winning ability of the Wigan flyer.
“For me it’s not a massive surprise that he’s starting,” Larsson said at Sweden’s pre-match press conference.
“I think he’s a very talented player who can offer something different to a lot of other players. I thought he had a good game when we played in Stockholm and he’s obviously one that we will need to keep our eye on.
"He’s always got a no-fear attitude, at least that’s the James I know from when he broke through with Sunderland. He tries things, he goes for it, he’s got a good left foot, and he’s not afraid to make a mistake. Not all players have got that."
"I expect a massive support for Ireland, they are well known for being fanatical and loud. There is a challenge in silencing them, and we can certainly do that. It would be very beneficial."
"You can’t forget our own supporters either, who give us great support away from home." Larsson pointed out.
Unlike his counterpart Giovanni Trapattoni, Hamren didn't name his starting XI 24 hours in advance despite the best efforts of some of the media in attedance and gave little clues to which players will be given the nod on Friday evening.
However, the mercurial Zlatan Ibrahimovic is set to be partnered up front by Norwich's Johan Elmander as the Swede's attempt to move clear of the Boys in Green and Austria, who play leaders Germany on the same night, in the standings.
Hamren has not denied the fact that there is huge pressure on his players as they attempt to qualify for their first World Cup for eight years.
"There is a huge pressure on players to do their best to win, and sometimes that means that they want to do too much, but you can forget that the players aren’t prepared or that they don’t want to win." He concluded.
