Arsenal fullback Gibbs: I've never been in better shape
Gibbs retains hopes of forcing his way back into England contention if his new approach can help secure a good run in the Arsenal side.
"It is the best I have felt physically," said Gibbs, who made his England debut in August 2010 when coming on as a half-time substitute for Ashley Cole against Hungary.
"I have always felt that when I am able to get a run of games, that is what I needed to kick on. I have always felt sure I could do that. Now I feel I am kicking on. I need to keep that going and stay fit. That is my main target.
"Since my thigh strain at the end of last year, I met someone new who has taken a good look at me physically and I owe him credit at the minute because he has kept me fit for the last eight to 10 months. I have to thank him for that."
