Manchester United are reportedly ready to move for Neymar after Paris Saint-Germain's president hinted that the superstar forward is up for sale.
The Brazil international joined PSG from Barcelona in a record £198m transfer two years ago and has scored 58 goals in 51 appearances for the club.
Off-the-field issues have plagued Neymar in recent months, though, and amid links with Real Madrid and Barcelona, Nasser Al Khelaifi appears to be ready to cash in.
"Things have to be completely different," he said in an interview with France Football. "The players will have to do more, work more.
"They are not here to have fun, and if they do not agree, the doors are open, Ciao! I do not want any more celebrity behaviour."
Spanish outlet Sport suggests that those comments have put Man United on red alert, and they are one of only a few clubs capable of signing Neymar.
The 27-year-old prefers a return to Barca, it is claimed, but Madrid have also showed an interest as they are looking to cram their squad with big-name stars.
