Former Manchester City shot stopper Joe Hart will retire from professional football at the end of the season.

The ex-England no.1 is calling time on his career, despite performing at a high level with Celtic.

Hart has been with the Scottish giants so far this season, with his deal running out in the summer.

Speaking in a video shared by Celtic, Hart explained: "As of June, I'm going to stop playing professional football.

"This is something that I've thought about for a while. There's no right or wrong time but the way this club works that I'm playing at at the moment there's so much on it.

"There's so much heart and soul poured into what we're doing as a football club, with the grand scheme of the club, the support base and the conversations that go on around it.

"There's obviously a conversation around the goalkeeping position for next season so I just thought it was important with the blessing of the club.

"I've had conversations with the club, with Brendan (Rodgers), with Stevie Woods. That if we get the message out it leaves one less thing that people need to speculate over."
