Bolton Wanderers defender Zat Knight is unsure what shape Aston Villa will be in this weekend.

Villa will face Bolton on the back of Saturday's 7-1 trouncing by Chelsea.

"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 former Villa defender 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. Unfortunately for them the semi is against Chelsea again."
