Chelsea defender Toni Rudiger is convinced by the potential of his partnership with David Luiz.

Rudiger has declared Luiz his "big brother".

He told chelseafc.com: "When I came new to Chelsea I was looking forward to playing alongside him [David Luiz]. That didn't happen that often in my first season here, so I was very happy for him he played more this season. He's a very good person and also an extraordinary football player.

"I get on with him very well. He's like a big brother and role model. He's a very like positive guy always and very important in the dressing room. I am very happy to play alongside him for another two years.

"Certainly we are both good with the ball, I think he has a bit of an advantage cause that's his game, but in terms of the more aggressive, there comes my place."
