Arsenal boss Mikel Arteta admits Mauricio Pochettino has been one of the biggest influences on his career.
Arteta takes Arsenal to Pochettino's Chelsea tomorrow. The pair are former PSG teammates.
"He [Pochettino] has been one of the most influential people in my career as a player," Arteta said.
"He took me under his wing and he looked after me like a little child. A little brother. He was a big part of the success I had in Paris.
"He has been a role model for me since that day, not only as a player but as a manager as well. He had a big say on that and I will always be grateful for what he has done for me."
