Two-time Premier League winner Joe Hart admits he was hurt when Pep Guardiola discarded him shortly after his appointment in 2016.
Hart was firmly on course to establish himself as a Citizens legend after winning two league titles, four Golden Glove awards and amassing 347 appearances for the club over eight seasons as the first-choice goalkeeper.
But the arrival of the Spaniard, who's playing philosophy is heavily reliant on a sweeper-keeper with world-class distribution, saw the England keeper snubbed, which has resulted in an incredible fall from grace.
Since being replaced by Claudio Bravo in the 2016/17 season and then Ederson Moraes arrival in the next marking his exit, Hart has made just 37 league appearances over four campaigns in the English top-flight.
Speaking to BBC One, the 33-year-old admitted moving on from City, first on loan to Serie A side Torino, West Ham and then eventually Burnley, affected his mental health.
"It will sound pathetic but it’s the truth, it’s not playing and not being wanted," the 75-time capped England keeper said.
"Things happened with the new manager at Manchester City, probably the most important manager in the world.
"He didn't even necessarily not like me, he just had a certain aspect which he didn't feel I was up to, and it kind of dropped from there."
Hart has not featured for the Three Lions since 2017 and is tipped to leave Sean Dyche's side in the off-season after being relegated to the bench at Turf Moor.
