Manuel Neuer has insisted that Bayern Munich can be beaten by Schalke this weekend if it does not put in a top performance.
Jens Keller's men were humiliated in a 6-1 defeat at Veltins Arena in the Champions League in midweek, triggering jokes in social media that they could concede double figures on their visit to the Allianz Arena on Saturday.
The Bavarians are yet to lose in the league this season and have won all their home Bundesliga games, but Neuer, who made his name starring in goal for Schalke before he joined die Roten, thinks his old side has the attackers to hurt the champions in Munich if they do not bring their best form.
"They don't have the players to sit back and defend - their strength lies in attack," the Bayern shot-stopper told reporters on Thursday. "Klaas-Jan Huntelaar and Jefferson Farfan don't like to work in defense, they prefer to stay up front. The same goes for Max Meyer and Julian Draxler.
"We know we are beatable, we know it's dangerous to let things slide. The coach always has new challenges for us.
"We've just worked together with Pep Guardiola for more than half a year now, but he does not see us where he wants us to be. That's the positive aspect: there is still room for further development."
The ex-Veltins Arena goalkeeper suggested Schalke's hammering at the hands of Real Madrid was an anomaly and does not think it is likely that Bayern will replicate that result this weekend.
"I know them better then anyone else, of course," he continued. "They wanted to show a great match againt Madrid. If they had had a better day they could have competed. Of course you can accept losing against that team, but not like that.
"They've shown a good start in the Bundesliga. We don't plan to see them off with six goals though, we just want to win the match."
Bayern has an all-but-unassailable 19-point lead in the Bundesliga over second-placed Bayer Leverkusen after 22 matchdays.
