Newly-promoted Leeds have signed midfielder Sean Longstaff from Premier League rivals Newcastle, it was announced Friday.

No fee was disclosed but British media reports said the four-year deal was worth an initial £10 million ($13 million), rising to £12 million ($16 million).

Longstaff, 27, in the final season of his Newcastle contract, has moved to Elland Road after being restricted to eight Premier League starts for his hometown club last term.

He made 171 top-flight appearances for the Magpies after coming through their academy, but fell behind Joelinton, Bruno Guimaraes and Sandro Tonali in the race for regular first-team football.

Longstaff is Leeds’ fifth pre-season signing following the arrivals of Lukas Nmecha, Jaka Bijol, Sebastiaan Bornauw and Gabriel Gudmundsson.

Leeds, promoted after winning last season’s second-tier Championship, are looking to re-establish themselves among the elite.

They were one of English football’s pre-eminent clubs of the late 1960s and early 1970s, as well as the last team to win the old First Division, the forerunner of the Premier League, in 1992.
