Antonio Rudiger says Chelsea must play "dirty" to disrupt Manchester City this Sunday.

The two clubs will meet for the second time this season at the Etihad, with City looking for revenge after their defeat in west London last year.

And Rudiger believes Chelsea must impose themselves physically against the champions.

"We have been there when it mattered," the German international said.

"We were the first team to beat Manchester City after all. We must be tougher.

"By now, we have a lot of possession, but we need to get something dirty back in our game."
