The Mali winger is reported to be on the verge of penning a pre-contract agreement with the Premier League but his manager hasn't given up hope of getting him re-signed.
Sako, 26, is out of contract in the summer and was linked with a £2 million move to Aston Villa in the recent transfer window, per the Birmingham Mail, as well as to Midlands rivals West Bromwich Albion.
While a move failed to materialise at the time, both the Mirror and Daily Star reported earlier this week that the Mali international is poised to sign a pre-contract agreement with Villa over the Baggies, with Wolves unwilling to match his current £25,000-per-week wages.
Having put off extension talks until the summer, Jackett admits that the Championship club will find it hard to keep hold of their star man but still haven't given up hope of getting a deal done, even with their promotion chances hanging in the balance.
“We’ll certainly be talking to him in the summer,” said Jackett, when asked if he still had hope of re-signing Sako. “I want him to stay but there will be no discussions until the end of the season and we know where we are.
“If there’s a chance of keeping him you’d probably take that chance.
“According to reports, there seems to be quite a few options. But he has to do the best for him, his career and his family.”
Sako has scored 37 goals in 122 total appearances since joining Wolves from Saint-Etienne in August 2012 for around £2.2 million, having stuck with the club during last season’s League One title-winning campaign.
Top scorer this term with 14 goals in 39 league games, the French-born attacker’s performances have helped Jackett’s side remain in the promotion hunt with two matches remaining but, with three points separating them from sixth-placed Ipswich Town, their fate is not in their own hands.
