Dimitar Berbatov admits he could have done better for Manchester United before this season.
Berbatov decided he had to make changes if he was ever to become the player United have wanted him to become since they paid Tottenham more than £30m for him in August 2008.
"I wouldn't say I have felt troubled here at United," he said. "I am not troubled. I am lucky. I have loved my time here.
"But I was disappointed with myself that I could not please all the supporters. I have said before the people of Manchester United are the judges and that is the way it should be. It is their team. I am a guest. A privileged guest.
"This crowd at Old Trafford is amazing. The way I feel right now, I'm not tired. I feel alive.
"I have always said I am so lucky to play here."
