Former Manchester City goalkeeper Willy Caballero has spoken about training under manager Pep Guardiola.
The Chelsea stopper was a back up keeper while at City under the Spaniard.
And Caballero only has positive things to say about Guardiola and the way he taught his players during training.
He said of Guardiola to TNT Sports: "It was like going to university with him.
"Every day you learn something new. If it's not on the pitch, it's when you're watching videos.
"The good thing is that he doesn't have problems with teaching a first-choice player or a substitute, a person who was 34 as I was then, or a youngster aged 18.
"He's a very good teacher and he's very good at correcting you."
