Manchester United manager Jose Mourinho could reportedly turn to Galatasaray defender Ozan Kabak in his search for a new centre-back.
The Red Devils are expected to strengthen the heart of their backline when the transfer window reopens in three weeks' time, having shipped 25 Premier League goals this term - the sixth-worst record in the division.
According to The Sun, Kabak has emerged as a target for Mourinho after impressing for Gala with his powerful presence in the air.
United scouts are said to have been sent to watch the 18-year-old, who is rumoured to be valued in the region of £20m.
Arsenal have also been tipped to make a move for the Turkey age-grade international, potentially driving up that asking price, although a separate report suggests that he could be snapped up for £7m due to a release clause in his contract.
