Chelsea midfielder Frank Lampard has revealed that Jose Mourinho is the "best" manager he has worked with in his career.
The 50-year-old managed the England international for three years during his tenure at Stamford Bridge as he guided the club to two Premier League title wins.
Mourinho has been linked with a return to Chelsea this summer after casting doubt on his future with Real Madrid.
Lampard told reporters: "For me, Jose was the best. He was the first manager I came across to have a particular way.
"He knew whether a player needed a leg-up or a rollocking. He formed a spirit among the team that was formidable. We didn't have a group mentality to win the league but he brought that in.
"And we have seen the same thing happening for him at Inter Milan and with his Real Madrid team."
Chelsea face off against Benfica in the final of the Europa League later today.
