Man Utd, Chelsea alerted as Marquinhos plans PSG transfer demand
PSG defender Marquinhos is ready to slap in a transfer demand.
The Brazilian is fed-up with his bit-part role this season and believes it is time to move on ahead of the January market.
Le 10 Sport says PSG president Nasser Al-Khelaifi is reluctant to lose Marquinhos, but won't hold the youngster against his will.
Chelsea failed with a bid for Marquinhos in August as an alternative to Everton defender John Stones and are expected to try again.
Manchester United will also be keen, having bid for the youngster last summer.
