Leeds United have reportedly demanded an option-to-buy clause in the agreement to sign Wolverhampton Wanderers winger Helder Costa on loan this summer.
Costa is expected to complete his move to Elland Road during the current transfer window after struggling to hold down a regular place under Nuno Espirito Santo in the Premier League.
Despite starring in the club's triumphant 2017-18 Championship campaign, the Portuguese only made 16 league starts last season.
According to The Mirror, Costa will have an option to make the switch to Leeds permanent at the end of next season.
Costa will once again hope play a key role in a successful promotion campaign after Marcelo Bielsa's side narrowly missed out on Premier League football last season.body check tags ::
