Manchester United have announced the agreement of a 10-year, 750-million-pound ($1.28 billion) contract with adidas -- the biggest deal in sports-licensing history.

The confirmation follows last week's news that Nike will stop producing United shirts after this coming season.

Nike confirmed Tuesday that it was bowing out of negotiations over paying for the right to manufacture the kit, refusing to match the offer put forward by adidas, which will net the club a minimum of 75 million pounds ($128 million) a year.

A statement on United's website said, "Manchester United plc has reached 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.

"For the 2014-15 season, Nike will continue in its role of technical sponsor and trademark licensee."

In a statement last week, Nike spokesman Nigel Powell said United were "a great club with passionate fans" and added: "We are proud to have partnered them for the last 12 years and will continue to sponsor the club until the end of the 2014-15 season.
