Mikel’s contract at the Stanford Bridge entered the final year this summer and negotiations can begin over a move at the beginning of 2017.
Mikel has so far struggled to get into Antonio Conte’s side and accepts that his time at the club could be winding up.
“When you have a year left as a football player, you have to start planning and start thinking about what’s going to happen at the end of the season. Yes, there are going to be rumours, yes, there are going to be conversations between club,” Mikel to Goal.com.
“When you have a year left, in January, you are allowed to talk to other clubs and sign a pre-contract or have an agreement so, yes, I will talk to other clubs because you never know what is going to happen.
“I’ve been here for a long, long time. I’ve spent 11 years of my life in this football club, it is my home.
“This season is the last at the club if my contract ends. I am quite relaxed about it, the future looks good.”
Mikel won three Premier League titles, two FA Cups, the Europa League and the Champions League.
