Manchester City boss Pep Guardiola has said Arsenal's Mikel Arteta had "a great, massive influence" on him and helped him become a better manager.

Arteta was Guardiola's assistant at City before taking the Arsenal job and the two sides meet in the fourth round of the FA Cup on Friday (20:00 GMT).

The Gunners lead the Premier League, with reigning champions City second.

"I had the feeling, we knew it when he was here, (about) his ability for City," said Guardiola on Thursday.

"I don't know my part on him but his influence on me was great, massive, so important in becoming a better manager.

"If I had left, Mikel would be here and he would be the best, absolutely."

Arteta became Arsenal boss in December 2019 and Guardiola, 52, said it was no surprise he had joined the Gunners, who he played for between 2011 and 2016.

"I am not a guy to say, 'no, you have to stay with me'," added Guardiola. "Everyone has dreams. We felt if one team could offer him (the chance) to be manager he would leave.

"I know he went to 'his' club, the team he dreams of. He's a supporter, for the fact he played there, he was a captain there. He loves the club.

"I remember when we were together here, when we scored goals, he'd jump a lot and celebrate - except against one team, Arsenal.

"People have to fly when they believe it is the best. Life is too short. Spend time in a place you believe suits you better."
