The England international striker scored a first-half brace on Thursday to take his tally of European goals for Spurs to 20, first lobbing Tromso goalkeeper Marcus Sahlman before coolly slotting home a second in the 30th minute.
Christian Eriksen added a third late in the piece to cap an impressive performance from Tottenham, who sauntered their way through large spells of the match.
Speaking to ITV, he said: "Everyone knows what he (Defoe) is capable of, his record speaks for itself.
"He is keeping himself sharp and fit and he's been excellent again tonight.
"There were two great assists from Lewis (Holtby) and (Erik) Lamela, but Defoe showed great movement as well."
"It was a perfect start," he continued. "It was important for us to get three points straight away.
"I think we had some good moments, it was a difficult game because of the injuries suffered throughout the game.
"But I'm very pleased in general by the performance."
