Paris - Harry Kane headed Tottenham into the Europa League last 32, the red-hot England striker's ninth goal in six matches earning Spurs a 1-0 win at Azerbaijani champions Qarabag on Thursday.
Kane's decisive second half goal assured the Group J leaders qualification into the knockout stages with a game to spare.
The North Londoners could probably have done without the 8,000 kilometre-round trip to the Azerbaijan capital just three days before the visit of Chelsea to White Hart Lane.
Despite the imminent arrival of the ailing Premier League champions Spurs coach Mauricio Pochettino fielded a strong side at Qarabag's Azersun Arena in Baku.
He made three changes from the XI that brushed aside West Ham 4-1 last weekend, with Kieran Trippier, Ryan Mason and Ben Davies starting.
Mousa Dembele, Danny Rose and Kyle Walker were rested, while Erik Lamela, Nabil Bentaleb, Nacer Chadli and Alex Pritchard, were sidelined.
The first hour was unforgettable, the game finally bursting into life when forward Son Heung-min smashed a shot from the edge of the box with the ball hitting the crossbar.
Shortly after Qarabag's keeper Ibrahim Sehic edged Eric Dier's angled shot wide.
Qarabag's Spanish winger Dani Quintana then forced Spurs' keeper Hugo Lloris into action down at the other end.
Having sprung to life Tottenham looked the more likely to break the deadlock, and in the 78th minute they deservedly took the lead.
Christian Erikssen fired in their umpteenth corner from the left with in-form Kane flicking in Son's header.
