Chelsea goalkeeper Willy Caballero has spoken of playing for Pep Guardiola at Manchester City.
Caballero had a season under Guardiola before leaving City for Chelsea in 2017.
He recalled to TNT Sport: "With Pep Guardiola, it's like going to university.
"I spent a year with him in City and I learned something new every day.
"He explains things when you're on the field, when you watch video - always. He has no problem teaching a 34-year-old, as if he is 18 years old. He is a good teacher."
