The winger has played just 87 minutes for Crystal Palace this season and was linked with a return to former side Wolverhampton Wanderers last week.
And with odds as short as 2/1, Wolves are the clear favourites to sign Sako before 3 February 2017.

However, Paul Lambert's side could face competition from a string of Championship rivals, including those at the upper end of the division.
Although relegation-threatened Cardiff City (4/1) are listed as second favourites with Bet Victor, four top-half sides - Derby County (6/1), Sheffield Wednesday, Reading and Norwich City (all 8/1) - also feature highly.
Derby and Reading could be the ones to keep an eye on, however, with Rams boss Steve McClaren still seeking his first signing since his return to Pride Park, and Reading on the verge of a takeover by Chinese brother and sister Dai Yongge and Dai Xiu Li.
Norwich, who have dropped off the pace over the past few months, could be interested if Robbie Brady is sold, although Wednesday have already agreed a deal to sign West Bromwich Albion wideman Callum McManaman.

Derby's win against Birmingham City on Tuesday moved them back to within a point of the Owls, who beat league leaders Newcastle United the previous evening.
