Arsene Wenger has accused Mick McCarthy of potentially damaging the international credibility of the Premier League following his decision to send out a weakened Wolves team against Manchester United.
McCarthy has been asked to explain his selection for Tuesday's 3-0 defeat at Old Trafford after the Wolves boss made ten changes to his side to face the champions.
His selection has been widely criticised in the media and now Arsenal boss Wenger has waded into the issue.
Speaking after his side's 1-1 draw with Burnley on Wednesday, the Frenchman said:"We compete with Manchester United over 37 games instead of 38.
"I believe it is a problem for the international credibility of the Premier League, but it is not my problem, it is a Premier League problem."
Meanwhile, a frustrated Wenger has hit out at the Premier League fixture compilers after being forced to play three games in six days this week.
The Gunners' weekend opponents, Hull City, have been spared the exertions of a midweek game.
"I think the Premier League has a basic promise to organise the fixtures in a normal way," he continued.
"The guy who organised the fixtures this season must have come out of a special school, because he is more intelligent than I am!
"For sure, he has never played football, organising midweek games in a week when you have a Europa League (programme).
"We have some teams who do not play at all. We play Sunday and Wednesday away and at home on Saturday against Hull, who have not played all week."
