Wolves sounded out a possible loan move for Crystal Palace winger Sako in the January transfer window and sources suggest they haven't ruled out moving for him again in the summer,
It's thought they have a number of other targets and re-signing Sako remains low down the list of priorities for now, in favour of younger options.
However, a loan deal, if the move was right for all parties, would suit Wolves and delight the club's supporters who took the Mali winger to their hearts during a successful three-year spell in gold and black.
A permanent deal would be unlikely given the finances it would take to bring for former fans' favourite back to Molineux. Sako turns 29 next month and Wolves would be reluctant to spend big on a player that left the club for free in 2015.
Sako is thought to earn £55,000 a week at Selhurst Park – around three times what he was on at Molineux.
He was signed by Stale Solbakken in 2012 from St Etienne and scored 38 times in three seasons before leaving on a free transfer.
A January move was scuppered by Sako suffering an injury, as well as his involvement in the Africa Cup of Nations, while Sam Allardyce had only just taken charge of the Eagles at the time.
The winger looks set to leave Palace this summer.
He has made just five Premier League appearances this season, all as a substitute and four coming in the 80th minute or later.
His Palace career started brilliantly with two goals in his first two games in August 2015, but he hasn't scored for the Eagles since and has been sidelined by first Alan Pardew and now Allardyce.
Any potential move would of course be dependent on Wolves avoiding relegation to League One. And Palace aren't yet sure of Premier League survival, sitting in 16th place, four points above the drop zone.
Championship rivals Derby County and Birmingham City were both said to have lodged £4m bids for Sako in January before the player decided to stay at Palace and fight for his place.
