Chelsea midfielder Frank Lampard admits former manager Jose Mourinho helped him make his game more "complete".
Lamps credits Mourinho for helping him make a huge leap in his career.
He told Chelsea TV: "It just involved self-confidence and a progression from what I'd been doing the season before, which had been a very good season for me with Ranieri.
"We'd got to the semis of the Champions League and I felt I belonged. Mourinho took that on and I was fortunate to be in a team that was very strong with a fantastic manager, and we became winners as a group.
"Personally I pushed myself on again with more confidence and my game became a bit more complete."
