Fulham are expressing concerns regarding the future of Aleksandr Mitrovic.

The centre-forward has been in outstanding form with club and country in recent weeks.

Mitrovic netted his 21st league goal of the campaign over the weekend, helping his team go top of the table with a 4-1 win over Barnsley.

According to reports in Spain, Unai Emery and Villarreal are assessing whether they can bring in Mitrovic in the January transfer window.

The Cottagers could receive a €16million offer, but it is unclear if the Championship club would risk selling their chief goal scorer as they aim to get promotion to the top flight.
