London (AFP) - Premier League giants Liverpool on Thursday announced that they have agreed the biggest kit supplier deal in their history with American sportswear manufacturer New Balance.

In 2012 Liverpool signed a six-year deal worth £25 million ($38.1 million, 33.4 million euros) a season with Warrior Sports, whose parent company is New Balance.

Their kits will be made by New Balance from next season onwards in a deal reportedly worth up to £300 million ($457m, €400m)).

"We are thrilled to announce this partnership with one of the world's leading sportswear brands, which is a record-breaking deal for the club," said Liverpool's chief commercial officer Billy Hogan in a statement.

"Like Liverpool FC, New Balance has over 100 years of heritage and a global footprint and they have a presence in many countries across the world, which will all feature LFC kit."

Liverpool's Premier League rivals Stoke City also announced that they will switch to New Balance from Warrior next season.

"Working with a brand with the global appeal of New Balance offers the club a chance to widen our fan base internationally, which is a very exciting prospect for us," Stoke chief executive Tony Scholes told the club website.
