Arsenal boss Arsene Wenger has hit out at next weeks PL fixtures which the Frenchman claims hands Manchester United an "unexplainable advantage." United are in action on Tuesday at West Brom, before they then have a break until the visit of Everton on the following Monday, February 2.

Arsenal, meanwhile, are away at Cardiff in the FA Cup on Sunday, before they travel to Goodison Park on Wednesday night.

"I feel that next week (Liverpool manager Rafael) Benitez has a case if you look at the way the fixtures are arranged," said Wenger.

"You can say that Manchester United have been extremely advantaged, unexplainably advantaged.

"But that is what we have to cope with.

"It is difficult to explain why one team plays on Tuesday and the others are all on Wednesday.

"It is unfair competition.

"Next week the fixtures are advantaged for Manchester United, who before had a point against Liverpool - I supported them when they had a case. But this week, I think Benitez has a case.

"Manchester United play on Tuesday at West Brom, after they play against Everton who will have played on Sunday, again on Wednesday night."

Wenger added: "I do not think you need to be a specialist in football to understand that in this case it is an unfair advantage for Manchester United.

"Will it have an advantage on the global season? I don't know, you would have to analyse that better.

"It is not Manchester United's fault, it is not Liverpool's fault. It is the organisers of the fixtures. They have a case to explain."
