Mikel has revealed Antonio Conte played a big role in ensuring Terry remained at Chelsea this season, and insisted that the fans believe the Blues can repeat their Premier League title haul from 2015 this time around if Terry remains fully fit and in the starting line-up.
"I think Conte played a big part in that contract that JT got," Mikel told Goal. "I think if JT said no, then obviously I don't think the club would have done that, but I think the fans as well got right behind JT and the fans really wanted him to stay.
"He is the leader, he is the captain and the fans really think with JT we have a better chance of winning the trophy again.
"I think everyone came together the fans, Antonio and the board did a massive job to make sure that John stays.
"I think JT will definitely be in Chelsea forever, so I can always wish him well, even when he retires, I think he will always be involved with this football club."
