Bacary Sagna has hailed the impact of Chelsea legend Frank Lampard at Manchester City.

Lampard already has six goals in just 13 appearances for City and his team-mates cannot speak highly enough of him.

"He is a great guy and he has fitted in perfectly," said Sagna of the former Chelsea player. "He showed here that he can score important goals and he is a great player.

"It's difficult to defend against him. He is a quick-moving player. You have to keep in shape. You have to keep alive.

"You have to focus even more. To play against these types of players is so difficult. All of them are top, world-class players.

"He was always very good. He has shown many times that he is a great player. As long as we have him on board, it's always good.

"His goal record doesn't surprise me because he is a great professional. He keeps working really hard in training.

"He always tries his best and he is always ready to come in, even if it's for 10 minutes. He is one of the best English players I have ever seen."
