Chelsea boss Jose Mourinho appears to have aimed a verbal swipe at Arsenal counterpart Arsene Wenger over the Blues' proposed deal to sell Juan Mata, with the Portuguese having suggested that he is always complaining.
Manchester United are expected to complete a transfer worth a reported £37 million for the diminutive Spaniard's services soon, with the player perhaps even in line to make his debut against Cardiff City next week if formalities are sorted in time.
Mourinho was quick to scoff at those thoughts, however, dismissing Wenger's views as just another complaint from the Gunners boss.
"Wenger complaining is normal because we know that is what he does," Mourinho was quoted by the Daily Star.
"When a player plays on August 20 then plays two week later on September 5 against the same club, this is normal.
"If Wenger sells Ozil to Man United I would be very happy because he is playing a very important player. Normally he should be happy we are selling a player like Juan Mata, but this is his nature."
The popular Chelsea manager, who returned to Stamford Bridge for a second spell in charge during the summer, appeared keen to turn the tables on Arsenal and spoke about an issue that he personally feels is more unfair relating to the fixture list.
"He says this is not fair. What i think is not fair is his teams always have the best days to play. In the Capital One Cup we had to play after 24 hours and they had 72 hours. That's not fair.
"This week, without a midweek game, what everyone wants to do is play before to have time to rest before the next week."One team plays Friday, another plays Sunday."Who plays Friday? Who plays Sunday? This is not fair.
"They always get the right time to rest - that's not fair," he added.
Chelsea and Arsenal are both in FA Cup fourth-round action this weekend, with Arsenal hosting League One outfit Coventry City at the Emirates Stadium tonight and Chelsea facing Mark Hughes' Stoke City on Sunday afternoon.
