ARSENAL are waiting for Luciano Acosta to join Paris Saint-Germain before they can complete the deadline day signing of Christopher Nkunku.
A move for the 21-year-old had appeared dead in the water with the 11pm deadline in the January transfer window looming.
But RMC understand that Acosta’s imminent arrival at the Parc des Princes could trigger the departure of the winger.
PSG boss Thomas Tuchel is desperate for cover for Neymar, who has been ruled out for 10 weeks with a broken metatarsal.
Twenty-four-year-old Acosta played alongside Wayne Rooney at D.C. United last season and is set to move to Paris in a move worth £7.5million.
Completion of the deal would free-up Nkundu for a move but it remains to be seen whether the Gunners can get the deal over the line.
