Spurs take on the Championship side in Thailand for their second game under new boss Postecoglou, following a narrow defeat to West Ham last time out.
Son missed that game after an extended summer break but is in training ahead of potentially facing Leicester.
Postecoglou can also bring in Tanguy Ndombele, who sat out the West Ham loss with a knock, while Eric Dier, Joe Rodon and Djed Spence are ready to make their first appearances of pre-season.
The Spurs boss has confirmed only Dane Scarlett is unavailable, telling reporters: “Obviously there were a couple who missed out last time who are available. We’ve also got a big squad here so not everyone will play.”
Rodrigo Bentancur and Ryan Sessegnon are injured, as well as Fraser Forster which should mean new signing Guglielmo Vicario continues in goal.
Tottenham should field a strong starting line-up with James Maddison due to play against his former club in a 4-2-3-1 formation.
Giovani Lo Celso and Destiny Udogie are both pushing for starts after impressing off the bench against West Ham.
Predicted Tottenham XI: Vicario; Emerson, Tanganga, Romero, Udogie; Hojbjerg, Bissouma; Kulusevski, Maddison, Son; Kane.
Injured: Bentancur, Sessegnon, Forster, Parrott, Scarlett
Absent: Lloris
Time and date: 11am, Sunday July 23, 2023.
Venue: Rajamangala Stadium
