Barcelona have extended their deal with kit sponsors Nike.

The Catalan giants announced the news on Friday night, calling the deal "a landmark in global football".

No details were reported on the partnership, which began in 1998, but Catalan newspaper Diario Ara claimed this week that it will be a 10-year deal worth £77m annually.

Barcelona president Josep Bartomeu told the club's official website: “Through this new agreement with Nike we are extending a strategic alliance for the club, while also reinforcing our global position, hand in hand with the leading global sports brand.

“We are excited by this new agreement and are confident that we'll be able to celebrate continued sporting successes together."
