Jose Mourinho believes English clubs have put themselves at a disadvantage by voting to change the transfer deadline date.
Next season the window will close before the start of the season but foreign clubs will still be able to buy Premier League players.
Mourinho himself backed the idea of an earlier deadline although United voted for it to stay the same.
Mourinho said: “As the head coach of Manchester United, obviously I am in favour of that.
“If I focus just on the training process of course I want to arrive, day one, I want to have my squad, my players, I want to work and travel with them in pre-season, I don’t want to be waiting for late decisions.
“There is another perspective, where I can also include myself because I am more than just the head coach, I have to share the problems the board has.
“Obviously when the decision is not uniform around Europe and all the championships, we are opening up to a disadvantage for the English clubs and that was the reason why Manchester United voted against.
“The market will be closed for us and is open for others and they can come to the English clubs, buy players, and they can leave English clubs without the possibility of a big action, so it’s another element of weakness.”
Premier League clubs voted 14-5 for the change of date with one abstention.
But Mourinho clearly believes those who voted for the change could be shooting themselves in the foot.
United got their business done early buying three of the four players Jose Mourinho wanted.
He believes the Red Devils strength means they should not be affected by the switch in deadline dates, but he is not sure about others.
He said: “Manchester United I hope are strong and powerful enough, to close our doors and say the ‘offer doesn’t matter’, ‘we have closed the market for buying, for selling’
“I expect my club to be acting that way but there are other English clubs that will be in risk, I hope it goes to the perfect situation – to close for every championship and not just the Premier League.”
