The South Korean started as the most advanced of Tottenham’s attacking quartet and scored two goals in three minutes to turn the game around, after Qarabag had taken the lead from the penalty spot.
“I’m delighted for him, he played very well,” said Kane, in an interview with the Ham & High.
“He ran in behind, he got two good finishes and he created a lot as well. We’re all delighted for him with it being his home debut, so hopefully there’s more to come.
“Obviously there’s been a lot of talk [about the striking options] but the manager’s happy with his squad, I think he’s come out and said that, so we’re happy.
“Sonny did a great job up there and we’re delighted for him to get the two goals. We’ve got a great squad, a lot of players in a lot of positions so we’ve got no worries,” he added.
Spurs’ desperate deadline day attempts to secure Saido Berahino suggest Mauricio Pochettino would have liked another out-and-out striker, but in Son he has a more than capable deputy.
The 23-year old was renowned for spectacular strikes in Germany, but his first two for Spurs had all the hallmarks of a seasoned goal-poacher.
Andros Townsend’s pinpoint corner fell to him six yards out, and he nipped across the flailing ‘keeper to get Spurs back on level terms.
His second strike arrived a couple of minutes later, after excellent link up play with Dele Alli, and he was on hand to slot away from close range again.
While it’s hard to judge his performance too meaningfully against opposition of the level of Qarabag, there is no denying he brings pace, directness and a real goal threat to Mauricio Pochettino’s side
