Pep Guardiola's biggest issue he must contend with at Manchester City is the ageing full-back crisis. At the moment, City have four full-backs over the age of 30. In June, Guardiola will lose Pablo Zabaleta and Bacary Sagna at right-back with the duo expected to depart the club following the end of their contracts.
Zabaleta, a nine-year veteran and self-proclaimed, "adapted Manc", will be a significant loss to City and the club needs to replace the Argentine rapidly.
Replacing both Zabaleta and Sagna won't be easy as the experience the two possess has proven invaluable at times this season. Nonetheless, the pair are regularly caught out for pace and no longer have the legs to bomb forward.
But who should Guardiola pursue? Here are five names the Spaniard should consider this summer.
#1 Kyle Walker – Tottenham Hotspur
Inarguably the most unlikely name on this list, Kyle Walker could prove invaluable for Pep Guardiola and offer the City boss a number of options when lining out his side on a weekly basis.
Walker has blossomed into a world-class full-back under the guidance of Mauricio Pochettino. The England international has been credited with becoming one of the club's most important players as unlike before, Walker is now capable of both attacking and defending in equal measure.
According to The Independent, City intend to test Tottenham's resolve this summer with a bid for the 28-year-old. Walker recently rejected speculation surrounding his future in a Facebook Live Q&A by repeating, "Tottenham till I die".
Whether City could convince Spurs chairman, Daniel Levy to part with one of his prized assets remains to be seen. Either way, Guardiola is barking up the right tree if he's targeting players like Walker.
