Manchester United are looking at a number of potential right-back signings including Bayern Munich's Noussair Mazraoui, a source has told ESPN.

United would like to add another right-back to their squad this summer, but it is likely to depend on Aaron Wan-Bissaka leaving Old Trafford.

Bayern defender Mazraoui is one of the names under consideration while the club has previously held an interest in Bayer Leverkusen's Jeremie Frimpong. A source has told ESPN that the 26-year-old Morocco international will be allowed to leave the Allianz Arena if Bayern's valuation is met.

United have signed 18-year-old centre-back Leny Yoro from Lille, but remain open to further defensive additions during the window.

There is still interest in Bayern Munich centre-back Matthijs de Ligt, although the German side are demanding a fee of more than 42 million.

United will consider offers for Wan-Bissaka, who has been the subject of interest from Galatasaray and West Ham United, and are hoping to return a fee of around 20m. The 26-year-old has one year left on his contract at Old Trafford.

Wan-Bissaka is likely to be part of the United squad which travels to Los Angeles on Wednesday for the start of their preseason tour with matches against Arsenal and Real Betis.

United are set to take a reduced number of staff to the U.S. amid plans to cut around 250 jobs from the workforce. A number of staff who have been told their jobs are at risk have been taken off the tour with the cost-cutting drive, led by new co-owner Sir Jim Ratcliffe and his INEOS team, set to accelerate.

United declined to comment when asked about the staff reductions.
