Tottenham and Manchester United have made an approach to Nikola Milenkovic's agent.
The Fiorentina defender's contract runs out next summer.
It's suggested there remains a chance he will extend his stay in Italy but there are key clubs involved in a transfer war.
According to La Nazione, AC Milan have shown the most serious interest but Spurs and United have also approached the player's agent.
Fiorentina's asking price of £22.7 million has not believed to have changed.
