David Bentley made the perfect start to his Tottenham career by scoring in the 2-0 win over Celtic at the Feyenoord Jubilee Tournament in Rotterdam.
The £15m winger came off the bench at the interval and rolled home a close range effort on 80 minutes.
Tottenham went ahead in the 24th minute thanks to Darren Bent's eighth goal in three warm-up games.
The striker latched on to a poor back-pass from Celtic's Paul Hartley and rounded keeper Artur Boruc to net.
Aiden McGeady was Celtic's liveliest player but the Scottish champions were second best for long spells and posed little attacking threat.
After a sluggish start to the game from both sides, Bent sneaked in to intercept Hartley's pass and slotted home from a tight angle.
Tottenham could have had a penalty when Bent tumbled under a Gary Caldwell challenge early in the second half. Bent went close in the 74th minute but his curling shot was well saved by Boruc.
Bentley sealed the win for Juande Ramos' team when Gareth Bale raced down the left flank, cut inside and his cross eventually found its way to Bentley for the easiest of finishes.
Spurs take on Borussia Dortmund on Sunday, while Celtic face the host club on the same day.
