Gabriel told Sky Sports: "I deserved more of an opportunity. Sometimes I played because my team-mates were injured.
“I did play and sometimes even after playing well, I'd go home sad, given that I was only playing because my team-mate was injured. I don't think I deserved that.
"I think I had the ability to play and to start games because I deserved to do so, or because I did well in training, but that didn't happen.
“Sometimes I'd play three or four games and if Arsenal lost, I'd be dropped and everyone on the outside would say, 'It's Gabriel's fault'.
"I think I played in four or five games en route to the FA Cup semi-final against Manchester City and I played brilliantly in that game. I played really well and I received plenty of praise.
“Then I think we faced Tottenham away and lost, I gave away a penalty in that game and lost my place in the team. I didn't play again."
