Sky Sports have reported that Wolves are interested in signing Maitland-Niles from Arsenal in the summer transfer window.
The Wanderers have made an opening bid of 15 million pounds for the 22-year-old, but the Gunners have rejected it.
The North London outfit want as much as 20 million pounds to sell the youngster - who can operate as a midfielder, winger, full-back or wing-back.
Talks between Arsenal and Wolves are going on, and Nunos side are expected to make a higher offer.
Maitland-Niles has been on the books of Arsenal since 2003 and has established himself as an important player in the first-team squad.
The 22-year-old made 15 starts and five substitute appearances in the Premier League, and played six times in the Europe League, once the EFL Cup and five times in the FA Cup for the Gunners during the 2019-20 campaign.
