Gareth Bale, Wayne Rooney and Luis Suarez have all been backed to quit their current clubs before the summer transfer window closes.
Tottenham winger Bale continues to be linked with Real Madrid as well as Manchester United, while United striker Rooney is a target for Chelsea.
Liverpool continue to insist that Suarez - a target for Arsenal - will still be at Anfield when the transfer window slams shut on September 2nd, but bookmakers William Hill believe the clubs in question may struggle to keep hold of their star players.
Hill's on Tuesday offered just 5/1 that all three are on the move before the transfer deadline, from an original 10/1.
William Hill spokesman Joe Crilly told Crunchsports.com: "There is still a distinct lack of movement where Gareth Bale and Luis Suarez are concerned right now.
"The only one who looks like he could be on his way is Mr Rooney, but of course, as with transfer sagas like this, as soon as one leaves the chances of them all going increases considerably."
