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 (S$51 million) a season with Warrior Sports, whose parent company is New Balance.

Their kits will be made by New Balance from next season in a deal reportedly worth up to £300 million.

"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.

"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."
