Nike reportedly decided to part ways with Manchester United due to the Premier League club's decision to display branding of the sportswear giants' rivals while courting potential new suitors.
The former English champions announced yesterday that they have sealed a 10-year kit deal with Adidas worth around £750m.
United teamed up with the brand after Nike confirmed that it would not be renewing its deal with the club beyond the 2014-15 season.
While some reports have claimed that the break-up in partnership was down to a financial disagreements, the Daily Mail suggests that Nike was annoyed that United displayed logos of its rivals at the Carrington training ground during talks with Adidas, Warrior and Puma.
Reports have stated that Nike saw the temporary display of another manufacturer's branding as unnecessary following the end of their period of negotiating exclusivity.
