With Wolves sitting 12 points clear at the top of the Championship standings, head coach Nuno Espirito Santo is already attempting to identify players that could be used in the Premier League next season.
Forward Rafa Mir has already been brought in from Valencia and according to the Express & Star, the Portuguese is now taking a look at Maddison.
The report claims that no offer has been made for the 21-year-old, who has contributed six goals and five assists in 24 league outings this season, but Nuno and his scouting team have been left impressed by the young Englishman.
Maddison is a key part of Daniel Farke's squad at Carrow Road, but the Canaries are currently in the process of reshaping their squad after a poor first half to the campaign.
The player only penned a new contract in the summer, with his deal now due to expire in 2021.
