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.
