Rennes have raised their asking price for Ismaili Sarr.
The winger is a target for Arsenal, where manager Unai Emery is a fan.
However, the Gunners won't get a clear run at Sarr and with competition increasing Rennes see their chance.
Rennes are now telling interested clubs that no less than €50m will bring them to the table.
Along with Arsenal, English rivals Watford and Leicester City are keen, as are AS Roma and Inter Milan.
