Tottenham are readying a bid for Arsenal midfielder Ainsley Maitland-Niles.
Spurs are understood to be monitoring Maitland-Niles' situation at the Emirates Stadium this summer as they look to bolster at right-back, says the Daily Mail.
The Gunners would listen to offers in the region of £20million for Maitland-Niles.
Mourinho has made a new right-back a top priority this summer after losing faith with Serge Aurier, who is set to leave the club during the transfer window.
Maitland-Niles is a central midfielder by trade but has excelled at right-back or right-wing back under Mikel Arteta.
And his versatility is viewed as a huge plus by Tottenham's recruitment team.
