Chelsea midfielder Frank Lampard has welcomed the return of Jose Mourinho.
The 34-year-old England midfielder broke the club's long-standing goal-scoring record this season and agreed a 12-month contract extension.
Lampard told BBC Sport: "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, and my personality in terms of football on a million miles. A lot of the reasons I moved on in the game is because of him.
"He's taken that (a winning mentality) everywhere he's gone with 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."
