Manchester City star Raheem Sterling says Mikel Arteta has transformed Arsenal since leaving City in December.

Former City No2 Arteta has made a big impression at the Emirates in his first 10 months in the role, leading the Gunners to FA Cup glory last season.

"He's a person that had a lot of say here," Sterling said. "The manager trusted him here and he had a lot of influence on the players here and the team as well.

"So I knew once he went into Arsenal that it would be a great opportunity for him but also he would definitely implement what he wanted to bring in.

"And he's a person that will put his foot down and not let things slide as you can see with the boys at Arsenal. They know if they don't run they are most likely not going to play."

He added: "We all knew before Mikel got in how much good football they could play, how technically good they were but probably off the field they weren't as aggressive as they are with Mikel.

"They run their socks off now, you can see why they benefited with some good results recently."
