Serge Aurier has occupied the first-choice right-back spot for the vast majority of this season, especially since Jose Mourinho came in as the new head coach.
Under Pochettino, Kyle Walker-Peters, Davinson Sanchez, Juan Foyth, and Moussa Sissoko also covered at right-back. Japhet Tanganga has also played there under Mourinho.
While Aurier has been rather successful going forward in a right-wing-back position for Spurs, he still raises eyebrows when defending in a flat back four.
Spurs failed to bring in a suitable replacement when they sold Kyle Walker to Man City, instead promoting Kieran Trippier. When selling Trippier, they again promoted an existing right-back rather than signing a new one.
One long-term option the Lilywhites have been linked to his young Norwich City full-back Max Aarons (Football Insider), however, The Athletic journalist Charlie Eccleshare has now cast doubt on a deal in his recent Q&A.
He claims that Norwich will charge around £50m for the youngster, a figure that Spurs will not be able to pay unless they qualify for Champions League football next season.
