Harry Kane scored from the penalty spot before Richarlison netted a second-half hat-trick as Tottenham hammered Lion City Sailors 5-1 in Singapore.
Kane started and captained Spurs amid links over a summer transfer to Bayern Munich and equalised for his side after Shawal Anuar gave the Singapore Premier League club a shock lead in the 14th minute.
Tottenham changed their entire XI at half-time and Richarlison made an instant impact scoring twice in the first seven minutes of the second half.
Giovani Lo Celso netted Spurs' fourth before Richarlison capped a fine individual and team performance with a tidy finish.

How Spurs hammered Lion City Sailors
Tottenham dominated throughout, recording 37 shots, as Kane volleyed wide the first good chance of the match inside four minutes before Lion City unexpectedly went ahead when Anuar turned in from close range with Pedro Porro at fault.
James Maddison shone in the first period, although he was consistently denied by goalkeeper Zharfan Rohaizad. Heung-Min Son, making his first appearance of pre-season, saw a goal ruled out for offside while Pape Sarr grazed the crossbar with a dipping volley.
Tottenham, though, forced an equaliser with the last kick of the half after Sarr was brought down in the area and Kane dispatched the penalty into the bottom right corner.
Ange Postecoglou's wholesale changes at the break didn't halt their dominance as Richarlison volleyed home within three minutes and then pounced on a mistake to head in.
The Brazilian striker saw two efforts disallowed for offside before Lo Celso found the net from close range.
Manor Solomon also hit a post with an angled volley but Richarlison was not to be denied in stoppage time, storming through the Lion City defence and rolling the ball past the goalkeeper.
