Martin O'Neill pinpointed the second goal as the key moment of our 2-1 win at Villa Park on Sunday.
Jermaine Jenas headed us into the lead in the fourth minute before a spirited comeback from the home side led by winger Ashley Young forced one fine save from Heurelho Gomes from Gareth Barry while Emile Heskey headed onto the crossbar.
We scored four minutes into the second half as well via Darren Bent and then looked the more dangerous side as Brad Friedel was forced to save from Luka Modric and Robbie Keane.
Villa eventually got a goal back five minutes from time but we weren't seriously troubled again.
"The first goal knocked us back a bit but it looked like we would get a goal, and coming into the dressing room at half-time there was plenty of confidence," said O'Neill.
"The second goal was a major setback, we were trying to chase the game and we became ragged and lost composure for next 10-20 minutes, and Tottenham took advantage.
"I felt we would always break them down and a goal was always on the cards, some moments it might not go in for you, but if you can get a few options together it might go for you. We shouldn't have let the setbacks kill us off."
