The Spaniard made 31 appearances in all competitions for Spurs last season, though injuries interrupted his campaign. Reguilon saw his position then come under threat towards the end of last term as Ryan Sessegnon thrived down the left in the defender's injury-enforced absence.
Tottenham also moved to sign the versatile Ivan Perisic on a free transfer from Inter Milan earlier in the window and the Croatian is more than capable of excelling in the left wing-back role within Conte's preferred 3-5-2 system. Perisic was the first of six arrivals this summer as Spurs sought to freshen up their squad ahead of the upcoming campaign - a campaign in which the Lilywhites will be competing in the Champions League.
Reguilon is one of a plethora of players expected to depart in the remainder of the window, as Conte aims to cull his squad in order to potentially fund further signings. Harry Winks, Japhet Tanganga, Bryan Gil, Tanguy Ndombele, Giovani Lo Celso, Emerson Royal and Matt Doherty are also believed to have been told they can leave this summer.
