Valenciennes chairman Francis Decourricre expects Paris St Germain to up their interest in defender Milan Bisevac.
The Serb has been at Valenciennes since his 2008 move from Lens but is being tracked by PSG, who were taken over by a group of wealthy Qatari investors in May.
Bisevac, who started his career at BASK, has impressed at Valenciennes but is thought to be keen on a move after the club's lowly 12th-place finish in Ligue 1 last season.
And Decourricre suggests he will not stand in his way: "I know of their (PSG) interest in the player, but the phase of negotiations has not yet begun. Perhaps they will start next week."
