Zat Knight is looking to heap more misery on Aston Villa this Saturday - admitting he has no regrets about quitting the club last summer.

Knight only lasted two years with his boyhood idols before he headed north for Bolton in a £4million deal.

It is not an experience he looks back on with any great fondness, even if it did fulfil a lifetime's ambition.

And when he meets them again at the weekend, the defender's concentration will be solely focussed on heaping even more misery on Martin

O'Neill following their seven-goal mauling by Chelsea on Saturday.

"I don't live in regret," said the 28-year-old, who boasts two England caps from the post-season trip to the United States in 2005.

"Going to Villa was a dream of mine and I lived it - but now I have moved on.

"I don't beat myself up about it. You could say it is stepping stones but that's football. It isn't something I look back on and wonder, what if?

"I did it for my own personal reasons."

Although Knight was on the wrong end of a beating himself at the weekend as Bolton were dismissed by Manchester United, their performance drew warm praise from manager Owen Coyle.

Martin O'Neill could not muster anything like the same sentiments about Villa's abysmal display at Chelsea, which all but wrecked their hopes of a top-four finish.

And for Knight, it brings a dilemma about how his old club will approach the weekend, given they have Chelsea to face again in the FA Cup semi-final on April 10.

"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 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."
