Although Tottenham need to primarily concern themselves with signing young players who can be potential difference-makers for the club, they have a sea of significant needs in their squad amidst a current placement of 17th in the Premier League, officially marking their worst season in existence.
Tottenham also can't underestimate the importance of signing quality backup players. Ange Postecoglou and some fans will point to injuries as an excuse for why Spurs have been so putrid this season, but the reality is that any Premier League team with aspirations of getting anywhere needs to understand that depth is important. Spurs don't have enough depth.
Although Tottenham have one of the world's finest right backs in Pedro Porro, they don't have anyone behind him as cover, save for inverting Destiny Udogie or Djed Spence. Tottenham need a true backup right back next season to take pressure off Porro and serve as an emergency option.
Tottenham don't have many RB options on the transfer market
According to a report from Graeme Bailey in an interview with Leeds United News, Tottenham are among the clubs interested in signing Southampton right back Kyle Walker-Peters, who will be a free agent this summer transfer window after contract talks between himself and the Saints went down the drain several months ago.
With Trent Alexander-Arnold off the table to Real Madrid, Walker-Peters is arguably the best option at right back on the free agent market, because he has extensive Premier League experience and is a solid two-way player who could comfortably back up a top team's starter, such as Porro at Spurs.
Walker-Peters spent three seasons with Tottenham as a promising backup before becoming an above-average starting right back in the Premier League for Southampton. Now in the prime of his career at 28, Walker-Peters will have several top teams in England lining up for his signature because he's free and he's one of the only established options at a scarce position.
As with any free agent, Tottenham have to be careful not to overpay in wages, because Walker-Peters is a prime candidate to get too much money as a 28-year-old with high demand due to his position and the league he has played in.
Other than that, Walker-Peters makes sense from a footballing perspective. Tottenham know him, and he knows the club. Known commodities are extremely valuable in backups, especially backup defensive players in positions where there isn't a whole lot of depth. Tottenham know they can depend on him to progress play and perform well in one-on-ones defensively, so if the price is right, reuniting with KWP isn't a bad idea at all.
