Fulham boss Martin Jol hopes Sir Alex Ferguson's criticism of assistant referee Simon Beck last week will not influence the officials' decisions in Saturday's fourth-round FA Cup tie at Manchester United.
The FA have sought an explanation from the United manager after he claimed Beck was 'shocking' in Sunday's 1-1 draw at Tottenham.
Dismal run: Fulham boss Martin Jol has never won at Old Trafford
Mark Clattenburg is in charge at Old Trafford, a ground where Jol has been on the wrong side of poor decisions before, most notably when his Tottenham side were denied a clear Pedro Mendes goal in 2005.
But the Fulham manager said he hopes Ferguson's comments will not play on the officials' minds on Saturday night.
Jol said: 'Hopefully not. It can be (a factor) but I can't look into their minds.
'I had a few situations, more than one or two, where something happened there. I've never beaten Man United but one or two people will remember that I should have beaten him 1-0 (in 2005). It was unbelievable.
'But I don't think it's about Alex Ferguson. He is shrewd and good, fantastic, and hopefully he is not having an influence on linesmen and referees. Especially not against us - hopefully.'
Under pressure: Referee Mark Clattenburg
Jol, whose two-year deal at Craven Cottage ends at the end of the season, said Fulham have triggered the 12-month extension clause in his contract, although Sportsmail understands an agreement has yet to be formally signed.
'They took that option so that was it from their side,' he said.
The Fulham boss also confirmed there had been no progress on a new deal for captain Brede Hangeland, who will be a free agent in the summer and has attracted interest from QPR.
Jol added: 'No, but he's our strength and we would be silly to get rid of him or sell him now.'
