Sako has been on the look-out for a new club all summer, and a report in the Birmingham Mail has claimed that his future will be decided in the coming weeks.
The 27-year-old winger, who made 124 appearances for Wolves before leaving this summer, has been linked with three top flight clubs in particular. The same report claims that Leicester City are in for him, whilst the Telegraph indicated that Aston Villa and West Brom have been showing an interest in the winger.
The Malian international is set to join one of the Premier League clubs, and the latest update gives hope to the buying club that a deal will be completed soon.
Teams want to start bringing their transfer targets in now to ensure they enjoy a full pre-season with their new teammates and manager.
Sako is set to have a deal wrapped up by next week, which implies the decision has already been made as to where the winger is set to move to.
All three teams would improve with Sako in their sides, and it promises to be an interesting announcement when the winger finally reveals which club he will be joining ahead of the 2015/16 season.
