Sunderland defender O'Shea holds no grudge against Man Utd boss Ferguson
O'Shea faces his old teammates this Sunday.
"It was hard, but I've always been level-headed and I know what happens in football. The manager asked to see me and told me he was thinking of different things, with the younger lads coming through and different signings being made. I'd always known it could happen one day and we left on good terms," he told the Guardian.
