He said: "I don't live in regret. Going to Villa was a dream of mine and I lived it - but now I have moved on."
Knight, who boasts two England caps from the post-season trip to the United States in 2005, has played in 35 games this season scoring one goal.

"Knowing Martin O'Neill they will have been in first thing on Monday morning watching the video of every single goal in minute detail," said Knight.
"It was a big defeat, which could work in two ways for us.
"They might look at the FA Cup semi-final now and think it is their best chance of achieving something, and that fourth place is out of their reach.
"That might mean they rest players, unfortunately for them the semi is against Chelsea again."
