Manchester United players are wearing replica kits when they play Premier League games.
Per The Mail, United's players are not happy at the way the official matchday kits are sized.
Summer signing Andre Onana is especially unhappy with the goalkeeper's top.
The players feel many of the official shirts are far too tight, to the point where they are restrictive.
Some players have even been cutting holes in their socks because they were so tight.
United and Adidas are said to be working to find a resolution to the matter at present.
