Cape Town - Crystal Palace's assistant manager Keith Millen says the club "do not want to lose any players" amid reports that Yannick Bolasie could be on his way to Everton before the season starts this weekend.
The Guardian claims Palace have already rejected an £18m offer from the Toffees, with their preferred price tag rumoured to be around the £30m mark.
The 27-year-old DR Congo international, who joined Palace from Bristol City for somewhere in the region of £350,000 in 2012, has been a key part in the club's resurgence in recent seasons.
With the new season just days away, Palace are naturally very keen to hold on to the talented winger.
Following the club's 3-0 win over Farnborough, Millen said: "I don't comment on reports or stories.
"The fact is Yannick is with us and he is a big part of what we're about. He has worked hard in training and speculation with players isn't great this time of year.
"It's unsettling but we have to try and deal with it. Until a deal is done he's in the squad and ready for the West Brom game."
He added: "We do not want to lose any players. We want to strengthen in the attacking areas, we need more goals in the squad and we are working hard to try and get more goals brought into the club. Yannick is a key part of that, whether he plays wide or as a 10 and we want to keep all our best players."
