Tottenham have joined the interest in Juventus defender Merih Demiral.
The Turkish central defender could become Jose Mourinho's first signings as Spurs boss, after club officials contacted the player's agent about a move.
United sent scouts to watch the Juve star, who has not played as many games since the summer arrival of Ajax defender Matthijs de Ligt.
The player himself wants out after becoming disillusioned under new boss Maurizio Sarri.
Demiral only moved to the Turin club in the summer.
The 21-year-old had impressed for Sassuolo after moving to Italy from Turkish club Alanyaspor last January.
