Barcelona midfielder Denis Suarez has criticised Manchester City for breaking promises during his spell at the club, according to a report in theDaily Mail.
Suarez, who made two cup appearances during his time with the Premier League club, left in 2013 for Villarreal having been loaned out to Sevilla.
The 22-year-old is now with Barcelona and has made eight La Liga appearances for the Catalan club, but had trouble fitting in at City, featuring mainly inconsistentlyfor the reserves.
"Mancini was very happy with me and told me I was going to make my Premier League debut. Then pre-season ended and it changed," Suarez told the Daily Mail.
"I went back to the second team and I don't think the coach knew who I was and in the first few games I hardly played.
"I couldn't understand it because after being told by Mancini that he was going to use me, I now found myself in the second team and there's a guy two metres tall playing in my position because he is stronger than me."
Suarez decided against going through the motions and instead looked to force a move that would see him playing regular football at a higher level.
"I was playing five or 10 minutes here and there for the reserves until after one game against Liverpool, when again I played no more than 10 minutes, I went to talk to City's scout in Spain, David Fernandez, and to Brian Marwood, and I told them if the situation didn't change I didn't want to stay. It just wasn't the way things had been sold to me."
Suarez could line up against his former side in the Champions League this week with Andres Iniesta currently sidelined with injury, and has claimed City still have a place in his heart, despite the move not going to plan.
"If it's the goal that gives the team victory, of course I will celebrate it," Suarez said when asked if he would celebrate scoring against his former club.
"That doesn't mean I don't have affection for City because they took a chance on me at an important time in my career."
