The 31-year-old has claimed that he was never told that he would be a reserve and that Allardyce was only interested in working with ‘his own’ players.
Diarra is now set to spend the rest of the season on loan at Rennes but may get a frosty reception when he returns to East London in the summer.
A section of West Ham supporters were jeering the French international in his final appearance for the club away at Arsenal and sung “Alou Diarra, you’re wasting your time” in reference to previous comments he made about joining West Ham being a waste of time.
It seems his long term future may lie elsewhere but Diarra is adamant that he was unfairly treated by the club and that he was fed up of fighting for a first team place.
“The coach did not refuse my arrival, but he didn’t want it either. I was just one additional player,” Diarra told France Football.
“I never gave up, but in the end you get fed up of fighting for nothing.
“Should I have spoken to the coach before I signed? I wanted to but he was always at training.
“I was handed a three-year contract, but he (Allardyce) wanted to work with his own players that have followed him for years.
“It is one of my worst memories because I have been cheated. I could not accept the situation any longer and went to meet with my representatives. They understood and I thank them.”
