Adidas CEO Herbert Hainer has indicated that he is unhappy with Manchester United's current style of play after the German company replaced Nike as the Red Devils' kit sponsors at the start of the 2015-16 term.
United manager Louis van Gaal has been heavily criticised for the ponderous, pragmatic football he has introduced at Old Trafford since taking up the top job at the club in 2014.
It is hardly paying dividends, as United are currently nine points off the top of the Premier League, and although Hainer insisted he is happy with how the fledgling relationship is going, he hinted that Adidas may not be so happy with Van Gaal, per German newspaper Suddeutsche Zeitung (via James Dickenson in the Express):
Business with Man United is going very well, we sell more shirts than expected.
