Felix Magath is hopeful Schalke can prove there is a way to beat Werder Bremen when the two sides meet in the Bundesliga.

Second-placed Bremen have not lost in 23 games, but Magath is aware all runs must come to an end.

"Albert Einstein would certainly have found a way to calculate the chances of them being beaten," he said.

"We want to try and be effective to get something out of this game.

"If we can remain courageous and decisive in defence, then we have also got to be ready to attack them."

Magath is not quite as convinced about his side's attacking ability though, claiming they "do have quality" up front, but that it has "not yet gained the necessary slickness".

That is something he believes opponents Bremen have in abundance.

"We can certainly learn something from watching Bremen play," he added.

Bremen have already taught several clubs a lesson this season, but their coach Thomas Schaaf appears to be particularly worried about tomorrow's penultimate Bundesliga game of the year.

"They are having an excellent season," he said. "Felix has got Schalke playing with lots of enthusiasm.

"As far as fight and determination are concerned, they have always given it everything, and their level of fitness is not only confirmed by the fact they have managed to earn points or turn games around in the last minute."

Schalke will be without the suspended Marcelo Bordon while Bremen striker Claudio Pizarro is unlikely to make his return this weekend.

He is making good progress from a persistent knee injury and has set his sights on returning before the end of the year.
