Muani has had a stellar season with Eintracht Frankfurt, contributing eight goals and 11 assists in 23 appearances.
And while he failed to make France's original 26-man squad for the tournament, he ended up going to Qatar as a replacement for the injured Christopher Nkunku.
He subsequently started the 1-0 group stage loss to Tunisia and could feature against England in the quarter-finals on Saturday.
Foot Mercato says Spurs and Liverpool are keen to sign the Frankfurt man.
Tottenham tried to acquire him in the summer but were beaten to the punch by the Bundesliga outfit.
