Arsenal manager Arsene Wenger believes Juan Mata's proposed move from Chelsea to Manchester United is unfair and feels the rules of the transfer window should be adapted, according to the Daily Mail.
The veteran Gunners manager is angry that the two clubs involved in the transfer do not have to play each other again this season - after playing a second leg last week.
But United will have Mata in their ranks when they meet the Blues' title challengers like Liverpool, Manchester City and, perhaps more pertinently, Arsenal. Maybe this is Jose Mourinho's anticipated logic?
With reports claiming that United have prepared a temporary helipad at Carrington as the Spaniard flies in to complete a £37 million club record transfer on Thursday, Wenger has bemoaned wrong timing.
"It opens again a little bit the opportunity of this transfer market because Chelsea had already played twice against Man United so they don't play again," he told reporters.
"They could have sold him last week but it opens at least the opportunity [to question] the dates of this transfer window.
"Some teams have already played twice against one opponent and some others not. I think if you want to respect the fairness for everybody exactly the same, that should not happen.
"I just think you would want that everybody is on the same level. Chelsea do not make the rules but maybe the rules should be a bit more adapted to more fairness."
The 64-year-old manager, who sold Robin van Persie to Manchester United in 2012, is puzzled by the fact that Chelsea willingly let the 25-year-old star go.
"I am surprised because Juan Mata is a great player and Chelsea sell a great player to a direct opponent," he continued.
United will face Ole Solksjaer's Cardiff City in a Premier League clash on Tuesday and Mata has been tipped to make an immediate debut for David Moyes side given their current squad troubles.
