Wolves owner Steve Morgan says they're aiming to make six summer signings.
He said: "We're looking for good quality players to add to the squad, around half-a-dozen players is probably right.
"The squad we have got is good, we have some really good players who will do more than hold their own in the Premiership.
"We were very successful last season, we won the Championship comfortably in the end with 90 points.
"Any team that can achieve that in the Championship where there are so many good teams must be a good team and we just want to add to the squad we've got."
