Adama Traore, Patrick Cutrone and Leo Bonatini will return to Wolves for pre-season, per the Express & Star.
Traore spent the second-half of last season with Barcelona.
But the Spaniard's spell fizzled out and it is unlikely Barca will activate their £29million option to buy.
Cutrone spent the last two years away from Wolves with spells at Fiorentina, Valencia and Empoli.
Bonatini has not been at Wolves since 2019, spending time at Nottingham Forest, Vitoria and Grasshoppers.
