West Brom's latest loan signing, Scott Sinclair, has blasted former boss Manchester City for the treatment he received during his time at the Etihad.
Sinclair, who signed for City from Swansea for £6.2 million, only played 190 minutes of Premier League football last season, and was regularly omitted from Mancini's match-day squad altogether.
And the 24-year-old has now hit out at the Italian tactician, and revealed his relief at having completed a summer switch to the Hawthorns.
"It's things like that, in the backroom, when he [Mancini] said he didn't give me a chance, which he didn't," Sinclair told Sky Sports.
"I even asked him, 'Why did you bring me in if you're not going to give me a chance? You've given me no game time to show what I'm about', and he couldn't really answer the question.
"As a player, if you're not getting a chance to play, then you are going to see the manager and ask him what is needed. So I did see him a few times, and we had our differences, but that's football."
Whilst Sinclair accepts that squad rotation is part and parcel of life at a team challenging for major honours like Manchester City, the former Swansea star conceded it was demotivating to be constantly overlooked, despite remaining fully focussed in training.
"Not being given an opportunity to play was frustrating, but that was the choice I made, I never kicked up a fuss," he added. "All I could do was put my head down and train every day.
"I definitely would think twice about doing it [moving to another big club] at this stage of my career."
However, Sinclair is delighted to have secured an Etihad exit, and is looking to put his disastrous spell at Manchester City behind him.
And now the Chelsea academy graduate is concentrating on making a good impression with the Baggies, in an attempt to complete a permanent move next summer.
"I now really hope I can settle here (at West Brom) and have a great start from Sunday onwards, score some goals, help to win games and if I'm happy enough then hopefully I'll stay."
