AS Roma have agreed a ten-year kit supply deal with Nike, reports SportsPro.
The American sportswear giant will supply all training and matchday apparel to the Serie A club, which was the subject of a US takeover last year, from the beginning of the 2014/15 season.
Roma terminated their current deal with Kappa in November in the hope of securing a more lucrative contract.
"This partnership is a fundamental step in that mission. Nike's dedication to football excellence and global brand building is aligned perfectly with our objectives. We are extremely excited about our future together."
Bert Hoyt, the vice president general manager of Nike Western Europe, said: "We're proud to partner with AS Roma, a club with great heritage. It’s a club that embodies strong characteristics, is recognized across the world and represents one of Europe's greatest cities. We look forward to developing a successful long-term partnership with them."
