Kurt Zouma says he's improved in every aspect of his game after last season's loan spell with Everton.
The defender has returned to Chelsea and Frank Lampard wants him to stay and compete for a place in his side.
After a season under Marco Silva, Zouma feels he can thrive at Stamford Bridge.
He said: It was a very good season for me. It was very good for my development. After my injury I was ready to play week-in week-out.
Going there I did that and improved myself technically and tactically in every aspect with the manager there. I am a better player.
Everything has improved in my game. I still have a lot to learn and to work on but I feel I have done a lot."
