Jermain Defoe handed us an early lead but we were then rocked by the dismissal of Didier Zokora after 21 minutes for foul on Elano.
That forced a reshuffle with Defoe off, Teemu Tainio on at right back and Pascal Chimbonda moving centrally but the 10 men defended magnificently, Paul Robinson produced two world-class saves and Steed Malbranque capped a night to remember with our second, clinching goal in the 83rd minute.
"I'm disappointed, the players are disappointed and I can imagine the fans ae disappointed," reflected Sven.
"We thought being at home we had a good chance of reaching the semi-finals, but Tottenham started very well.
"They caused us problems, scored early and created one or two more chances. We got away with it at 1-0 at half-time. We played 11 against 10 for 70 minutes and in the second half we controlled the game - but we could not score. Paul Robinson made two very good saves and that was that."
Sven Goran Eriksson couldn't hide his disappointment after our Carling Cup victory ended his City side's 100 per cent home record this season.
