Mikel has along with defender Ricardo Carvalho been linked with a move to Inter this summer.
He told the club’s official website: “I think I have played a lot of games and I am happy with that achievement over the course of the season and the way I have contributed.
“I will be disappointed when the season ends because I love coming in here every day and training with the guys, and the banter that we share but we have a few weeks away to rest.”
Mikel joined Chelsea from Norwegian side Lyn Oslo in 2006.
