Germany coach Joachim Loew admitted his team have much to improve after they laboured to a 2-0 friendly win over minnows Israel on Thursday in their final warm-up game before Euro 2012.

The Germans open their Euro 2012 campaign in Group B against Portugal in Lviv, Ukraine, today week, but after losing two of their last three games, Loew’s side boosted flagging confidence against minnows Israel.

A first-half goal from Bayern Munich striker Mario Gomez put the hosts ahead before Leverkusen’s Andre Schuerrle came off the bench to double the lead eight minutes from time with a superb long-range strike.

Having suffered a shock 5-3 defeat to Switzerland in Basel last Saturday, the Germans managed to avoid their third straight defeat of the year, after also losing to France in February, but must still improve, according to Loew.

“It was a pretty decent final test, this will give us some momentum,” he said. “Not everything ran smoothly, but taking a victory into next week will do us good.

“We still have to improve and work on finishing our goal chances, the organisation was better, but there is still much to do.”

Germany had far more shape and purpose in their attack than they showed in Basel, but captain Philipp Lahm succinctly summed up his team’s laboured performance.

“We have sensational quality in the squad, now we just have to show it,” he said.

“We had some good combinations. It can’t always go perfectly, which is why the victory was important.

“The fact not everything worked today is normal, because we haven’t played together for two weeks.

“We’ve showed in the last few years what that it does work and it’s important we hit the ground running in our first game.”

Germany’s chances against Portugal received a boost with the news Bayern Munich midfielder Bastian Schweinsteiger should be fit for the opening game.

The 27-year-old injured his calf in Bayern Munich’s Champions League final defeat to Chelsea a fortnight ago and sat out the win over Israel, but should be fit.
