Michael Vick has said that he is "proud" of the pre-season performances that helped him win the Philadelphia Eagles' starting quarterback job.
Head coach Chip Kelly confirmed that the 33-year-old would take the role for the 2013 NFL season yesterday.
Speaking at a press conference, Vick said: "I chose to come back for one reason, and that was to help this football team win football games. I thank Coach Kelly for the process we all had to go through, and it doesn't stop here. This is day one and I still have to prove myself each and every day.
"It's gratifying to know I've had to come back and work for everything and it wasn't given to me. I'm proud that I got the best out of myself when I needed it, and it's going to be needed and required a lot more. If I can take that same approach, then hopefully good things will happen for this team.
"There's nothing better than that, knowing you have to be at your best. I know it's not going to change because coach is going to continue to coach and treat us the same way he has been. I can't let these guys down."
Vick lost his place in the starting lineup mid-way through last season after sustaining a concussion.
