Defender Lars Jacobsen believes Denmark have to “deliver on the highest level possible” against Germany if they are to secure progress to the Euro 2012 quarter-finals.

Germany have won their first two games of the tournament and sit in top spot in Group B heading into Sunday’s match, though they could still feasibly be knocked out should they lose to the Danes, and Portugal beat Netherlands in the night's other fixture.

There have been suggestions that Joachim Low may make changes to his line-up for the clash at Arena Lviv, but Denmark right-back Jacobsen believes he and his team-mates will need to be at their best whoever their opposing players are.

“Germany were my tip before the tournament - they have obviously played very well and it’s going to be a tough match for us,” Jacobsen said.

"They are pretty much assured of qualifying so they may play a slightly different team against us but we’re going to have to deliver on the highest level possible, all 11 players are going to have to be at their best for us to get a result and qualify. We also need a bit of luck with the other game.”

Denmark have not played in the knockout stages of a major tournament since Euro 2004, but Jacobsen feels the current crop has the perfect blend of youth and experience to advance.

“We’ve had some generational changes over the past year in the national team. We’ve had a difficult period in international football where we have missed out on a couple of qualifications in a row so gradually there have been more and more changes.

“Some of the young players have really broken through in the Euro 2012 qualification phase. Christian Eriksen and Niki Zimling have both really made an impact on the team there have been other young players who have really contributed a new energy to the team.

“It’s not always necessary to completely overhaul a team, some new players have joined and worked well with the existing players to really help take us forward.”

Morten Olsen’s side began their Euro 2012 campaign with an impressive 1-0 win against Netherlands but then suffered a painful 3-2 defeat at the hands of Portugal, having fought from behind to level the scores at 2-2 before Silvestre Varela snatched a late winner.
