The 27-year-old winger enhanced his reputation further last season after netting five times in 23 Premier League starts, setting up three.
The France-born flier appears to be one of these players who is constantly linked away, though a move never seems to materialise.
However, Bet Victor have Everton as 1/1 favourites to sign him before the transfer window closes, usurping Leicester City - who are now 3/1 - as the club most likely to sign him.
The Toffees' Merseyside rivals Liverpool are third favourites behind Leicester on 6/1 - and the Reds might be in the market for a winger after Jordon Ibe was sold to Bournemouth for £15 million last week.
Whoever signs him, it won't be cheap. The Mail reported earlier this month that Crystal Palace would not part company with the Democratic of Congo winger for less than £28 million.
Everton and Liverpool have the money, but time will tell if either club is genuinely interested.
