Darren Bent knows he's left an angry Sunderland over the manner of his move to Aston Villa.
Bent slapped in a transfer request on Sunday night and was in Birmingham on Monday for his medical.
Bent admits he regrets his goal-laced spell with the Black Cats ending the way it did after just 18 months.
He said: "I am sure Steve Bruce and the fans will be disappointed and I am sorry it ended the way it did.
"But I showed my passion for the club in the two years I was there and now I am looking forward to the future with Villa."
