Getafe's left-sided midfielder Marc Cucurella - on loan from Barcelona - is being tracked by Chelsea, Napoli, Borussia Monchengladbach and Bayer Leverkusen ahead of the summer transfer window.
Barcelona have an arrangement to sell their loanee to Getafe in the summer for €6 million and the Catalan giants stand to earn 40 per cent of his next transfer.
Getafe's permanent deal with the Spain under-21 star will include a buyout clause of around €25m (£23m/$28m), which is attractive to Napoli, Gladbach and Leverkusen.
Chelsea have been scouting Cucurella - who can also play at left-back - but are only thought to have him low on their shortlist with the likes of Leicester City star Ben Chilwell and Porto defender Telles being greater priorities.
Barca are not keen on bringing back Cucurella despite his impressive performances that have helped Getafe compete for a Champions League spot with the likes of Sevilla, Atletico Madrid and Real Sociedad.
Marcos Alonso has come back into the Chelsea line-up in recent weeks but came close to a move to Inter in the winter transfer window. Italy international Emerson Palmieri, meanwhile, is likely to return to Serie A in the summer.
