Barcelona have until Friday to re-sign Gerard Deulofeu from Everton, although Milan are also interested in making his loan move permanent.
The 23-year-old winger linked up with the Rossoneri on a six-month loan in January after failing to make an impact under Toffees boss Ronald Koeman in the first half of last season.
The Serie A club are keen to retain his services, while Barca want Deulofeu back after he impressed for Vincenzo Montella's side during his short-term stay in Italy.
The Catalans included a buyback clause in the deal that saw the Spain international join the Merseysiders in 2015, but they only have a few days left to take up the option.
However, the Spanish giants must convince Deulofeu that he has a future at the Camp Nou, with new head coach Ernesto Valverde keen to deploy him on the right side of their attacking trident.
