Fulham are considering Villarreal's big-money offer for Andre-Frank Zambo Anguissa following an impressive loan spell with the LaLiga club, the PA news agency understands.
The 24-year-old made a deadline-day switch from Marseille to Craven Cottage in August 2018 but struggled to make an impact as the west London club were relegated from the Premier League.
Anguissa, who still has three years left on his Fulham contract, was shipped out on a season-long loan to Villarreal last July and the midfielder looked back to his best in Spain.
Villarreal had the option of making the transfer permanent at the end of the season as part of their loan agreement. Fulham are understood to be considering an offer in the region of 25 million euros (£22.2million) that suggest the clause has not been triggered.
