Manchester United's listless style of play under manager Louis van Gaal has even drawn criticism from their kit manufacturer Adidas.
The German sportswear giants agreed to sponsor United again when they signed a 10-year contract worth £750 million – the biggest deal in football history – starting from the 2015/16 season.
Van Gaal has come under fire from many quarters for the style of football he has implemented at Old Trafford, with his side having scored just 24 goals in their 20 Premier Leagues outings this term.
Red Devils fans have been chanting "Attack! Attack! Attack!" at numerous games in the hope of seeing some exciting football, and Adidas CEO Herbert Hainer admits the team could improve in that regard.
Hainer told Suddeutsche Zeitung: "Business with Man United is going very well. We sell more shirts than expected.
"We are satisfied, even if the current playing style of Man United is not exactly what we want to see."
