Chelsea midfielder Frank Lampard has admitted that he improved as a player under the guidance of manager Jose Mourinho.
Lampard worked with Mourinho when the 50-year-old arrived in the Premier League in 2004, and the England international credits the Portuguese boss with helping him further his career.
The 34-year-old told the club's official website: "He's a great manager, I've said it a million times to the point of boring people, but I'm very fortunate to have worked under him before.
"He took my game on a million miles. A lot of the reasons I moved on in the game are because of him.
"He creates a spirit in his squads that you can see from the outside is very, very strong. He's a top-class manager, we all know that."
The former West Ham United midfielder became Chelsea's record goalscorer last season.
