Joe Hart has announced his intention to retire from professional football at the end of the season.
The Celtic goalkeeper will call time on his career after three seasons in Scotland, during which time he has won two cinch Premiership titles, two Scottish League Cups and one Scottish Cup.
Brendan Rodgers' side remain in contention for the Premiership crown and are in the last eight of the Scottish Cup this season.
Hart, who won 75 caps for England, has enjoyed a glittering career which started at Shrewsbury Town before a move to Manchester City where he lifted the Premier League title in 2011/12 and 2013/14.
Celtic boss Brendan Rodgers told the club's website: "Joe has enjoyed a phenomenal career and I know will be huge miss to the game when he finally retires from playing football in the summer.
"For all he has done in football, Joe deserves huge praise and congratulations, he has been such a brilliant asset to Celtic of course and the wider game at the highest levels, domestically and internationally."
