Everton want to keep the 24-year-old France international but the final decision will ultimately be Chelsea's and Zouma's.

"I don't know yet. We have five more games to play and then we will see," said  Zouma when asked about his future.

"I am very happy. My aim was to come and play and improve myself and I think I have done here. I hope we will finish the season very high."

Zouma had a new partner on Sunday in Phil Jagielka, a late replacement for the ill Keane minutes before kick-off against Arsenal, and was impressed as the club captain scored the only goal in a 1-0 victory.

It was Everton's third successive win and they have also kept five clean sheets in the last six matches despite the defence set-up changing regularly.

"We have more confidence and every one defends as a unit. Now everyone understands each other," added Zouma.

"We hold the ball a bit better, we are more compact as a team as we defend together and attack together.

"We are confident, are playing forward more and are playing better and we believe, but the season hasn't finished yet so we have go again next week and get a win.

"It wasn't difficult (to play with the change) because we're used to working hard in training altogether.

"The manager mixes defenders and we all know each other. Playing for the first time with the skipper has been good for me and he brings good experience for us: me, Michael and Yerry Mina so we try to take all the experience he has.

"And his first goal in the Premier League this season was very important."
