But he reckons the manner of Spurs' performances have still sent out a message to the rest of Europe.
The north Londoners scored 18 times in the group stage, a record for a rookie team and only two short of the all-time mark of 20 set by Manchester United's treble winners.
There were also an incredible 29 goals in total in their six games - 38 in eight when the qualifying round is included.
Defoe said: "I think it sends a good message because we're scoring a lot of goals at this level.
"It's always important not to concede as well but we created a lot of chances, which is always good.
"We're always going to do that with the players we've got anyway.
"I suppose now teams, when they come up against us, know they're going to be difficult games."
