Spurs went ahead three times during the game, only to be pegged back by a resolute home side.
By confirming top position, they will now face a team who has finished in second place in their respective group - thus avoiding the likes of Barcelona and Real Madrid.
“Yeah, [we are] delighted,” Defoe told Sky Sports.
“We started bright and got the early goal then eased off a bit [in the first half]. It would have been nice if we won the game, but we'll take that.
“We worked so hard last season to actually come here, so when you're here you have to make the most of it. We have scored a lot of goals, but it's important not to concede as many.
“We take each game as it comes, the way were are playing and the amount of goals we are scoring - and we create a lot of chances. There are still one or two injured [players] to come back so you never know but everything is looking good at the moment.”
“It is very important for us to finish on top,” added William Gallas.
“We could have done better because we conceded three goals and I think everybody is a little bit disappointed, but it's good we finished on top.”
Spurs could well have claimed all three points, but Gallas bemoaned a series of “strange” decisions from the referee.
“I don't want to say anything about the referee, but tonight he was a little bit strange. I don't know about their penalty, but we have to try and accept it,” he concluded.
