Frank Lampard has defended his Jose Mourinho’s action for selling Kelvin de Bruyne during his time at Chelsea in 2014.
Mourinho sold de Bruyne to Bundesliga side Wolfsburg and he joined Manchester City in 2015 before making a name for himself as one of the best midfielder in the Premier League.
However, Lampard says Mourinho was right to let his former team-mate De Bruyne leave Chelsea because the Blues had other options.
"I think it was a difficult time for the club because they had (Eden) Hazard, Oscar and Willian had just signed," Lampard told BT Sport.
"So you couldn’t play them all. Kevin De Bruyne, his development wasn’t where it is now.
"He was very good at a lot of things in his game, I think now he’s great in his game
"Of course it’s easy with retrospect with Chelsea and say ‘why did you let him go?’.
"But sometimes players develop at different rates. Kevin has gone away and made himself a world class player in my opinion.
"He had good pace, he had good passing, he had good dribbling skills
"But at that point he couldn’t get into our team and one thing he had was a lot of ambition.
"You could see he was upset he wasn’t playing and I don’t mind that in a young player. He wanted to go away and prove he was a player."
Chelsea will take a trip to Selhurst Park to play against Crystal Palace following the international break.
