Manchester United veteran Ryan Giggs says the manner of last season's title surrender to Manchester City "hurt" manager Sir Alex Ferguson.
Giggs admits losing the title in the final minutes of the season was difficult to bear.
"No one wanted to experience disappointment again," said Giggs. "Sitting in the dressing room after the final game was horrendous.
"To lose on goal difference was cruel, so everyone was hurting. That will have stayed with the manager over the summer. It's been one hell of a motivation."
