Tottenham are just one point above the relegation zone with several players expected to leave in the summer.
According to journalist Pete O'Rourke, Manchester City have a ‘long-term’ interest in Porro, 26, despite letting him leave permanently in 2022.
It’s understood that Pep Guardiola’s side are looking to sign a long-term replacement for former right-back Kyle Walker.
Porro has been a bright spark for Tottenham this season, registering one goal and five assists in 37 appearances across all competitions.
