Manchester United are reportedly at the head of the queue for Fiorentina defender Nikola Milenkovic.
The 23-year-old joined La Viola from Partizan in 2017 and has made 118 appearances for the Italian giants in all competitions, including 22 outings during the 2020-21 campaign.
Milenkovic's contract is due to expire next summer, though, and it has been suggested that the Serbia international will not be penning an extension with his Serie A club.
Juventus and Inter Milan are among the teams to be credited with an interest, but according to La Repubblica, United are leading the race to sign him during this summer's transfer window.
The report claims that Milenkovic will be allowed to leave Cesare Prandelli's side for the right price ahead of the 2021-22 campaign, with the two-time Italian champions setting a value of €35m (£31m).
United have conceded 30 times in their 23 Premier League matches this season, including three in Saturday's 3-3 draw with Everton at Old Trafford.
