Triaud claims West Ham United would have been a better destination for the Morocco international.
He told So Foot: “Sunderland didn't meet our criteria.
“Laslandes went to Sunderland and he ended up depressed. They were against Laslandes. No, West Ham was better. Actually Marouane would have played one season with them, they would sell him, then they would pay us.
“I told Marouane: 'you choose'. And he called a press conference to announce he would be staying.”
