Bolton Wanderers boss Gary Megson hopes none of his players repeat last season's performance of former defender Abdoulaye Meite against Manchester United today.
Megson was stunned when his Ivory Coast defender Meite decided he had had enough at half-time of this fixture in March.
The Trotters chief recalled: "I have never seen anything like it. He just started taking his kit off, put his towel round him and said 'That's it, I've had enough'.
"He didn't say anything to the physio or the doctor, he just said he wasn't match-fit.
"It was strange because he had been at the African Nations for a month and hadn't missed a day of training since then."
Bolton lost 2-0 and Meite has since been flogged to West Brom.
Megson added: "It's always a tough task to go to Old Trafford without that kind of thing happening."
