Former Chelsea star John Obi Mikel has a warning for boss Mauricio Pochettino this week.

Mikel believes that Pochettino should be facing the sack if he cannot get more out of the team.

The former midfielder, who won the Premier League and Champions League at the club, stated that Poch must go if results do not improve.

"We've given them time now. it's been half a year. Now it's time to win. In Chelsea there's no time. You have to win - that's our motto," Mikel told Sky Sports at The Best FIFA Football Awards in London.

"If you don't win, Roman gets you out of the door and gets someone else. So I think that should be the new owner's way of thinking - you have to win. If you don't win, what's the point of being at Chelsea?

"The excuse of trying to review is done. So now we have to win games, play better, improve and try to compete. This year, knock it on the head now. Next year we need to be up there. We have to keep building the team. Everybody says we've spent a lot of money and we have.

"We've bought a lot of good players and they need time to improve, and get better as a team. I think Poch is a really good manager. He does really well with young players and with the team. We need a striker, a point-man who scores goals."
