are lining up a £72million bid for Lazio midfielder Sergej Milinkovic-Savic - but the Italian club are demanding £90m, according to Sky.
The Old Trafford club see Milinkovic-Savic as a possible replacement for Paul Pogba
should he leave the club this summer.
Milinkovic-Savic is keen on the move but, having signed a new contract in October, will not force a departure through this summer.
New PSG sporting director Leonardo is interested in the Serbia international, while Maurizio Sarri's Juventus are also monitoring the situation.
Milinkovic-Savic, who joined from Belgian club Genk in 2014, has registered 31 goals in 138 appearances for Lazio.
However, he had a difficult campaign last season, scoring only seven times and getting four assists.
French World Cup winner Pogba's future is very much up in the air at Old Trafford following comments made by his agent Mino Raiola, and Milinkovic-Savic currently tops their list of replacements.
