Wolves have apparently lodged a £2.3 million bid for the Guinae international, after being impressed with his performances in the past season.
Sylla netted seven goals in 34 appearances for Anderlecht, and his physical presence caused defences a great deal of problems.
Wolves are known to be on the hunt for a striker, as they continue to try and replace Benik Afobe, who left to join Bournemouth in January.
Wolves brought in Joe Mason at the start of the year, but Kenny Jackett has already expressed a desire to find a new partner for the former Cardiff City man.
Sunderland are also on the hunt for new additions, as they aim to bolster their squad.
The Black Cats have funds to spend this summer, but Allardyce is keen not to overspend and could see Sylla as a bargain buy.
