Louis van Gaal
United's agreement with Adidas begins from the 2015/16 campaign.

Louis van Gaal's imminent arrival at Manchester United has been boosted by the news the club have clinched the biggest kit deal in sporting history worth £750m after confirming Adidas as their new shirt manufacturer from the 2015/16 season.

United have ended their relationship with Nike after 13 seasons with the American company, signing a record-breaking kit deal with Adidas in a agreement thought to be over 10 years.

A club statement read: "Manchester United plc has reached a ten year agreement with adidas for a global technical sponsorship and dual branded licensing deal for a minimum guarantee of GBP 750 million, subject to certain adjustments, beginning with the 2015/2016 campaign."

The deal quashes any fears that after the club failed to qualify for the Champions League last season, that a dip in success would affect their off-the-field earnings and standing in world sport.

Just weeks after Arsenal announced Puma as their new kit manufacturer in an £170m deal, United have eclipsed the agreement, having clinched the biggest deal in English football.

Confirmation of the agreement comes just days before new manager Van Gaal is set to officially begin his reign at Old Trafford, and the Dutch coach's future transfer dealings are likely to have been dramatically affected by a deal which is worth £75m per season to the 20-time English champions.

After guiding his Netherlands side to third in the 2014 World Cup, Van Gaal will begin his United tenure on Wednesday.

"That is no problem for me, I don't need a holiday," Van Gaal insisted. "It's great to have such an exciting challenge. To work daily with young people is something that I don't need time off to rest for.

"I'm looking forward to it. I've only met two people from the daily management at the club - the chief scout and the chief executive officer. And I've met two of the owners. It's time that I get to know more people at the club.

"I hope the group in Manchester will become like this one. We have to sing from the same hymn sheet.

"I hope at Manchester United I can do my best. I will do my best. Whether that's enough for the fans I will wait and see, but I genuinely hope that will be the case."

Van Gaal has already signed Ander Herrera and Luke Shaw this summer and further additions are expected before the season begins on 16 August.
