The lads dominated the game and took the lead against a stubborn Norwich midway through the second half thanks to a Gareth Bale strike, but a late Vertonghen own goal was followed up by a Simeon Jackson tap-in to send the Canaries through to the quarter-finals at our expense.
"It's hard to take. It's never easy to lose any football match but the way we lost this one makes it tough. We had all of the possession in the first half and I don't think Norwich had a shot at goal,' Daws told tottenhamhotspur.com.
"We played a little bit too slowly but came out in the second half and we got at them. After Gareth scored I hoped we would go on and get a second and even a third goal. We felt in complete control.
"Norwich got a goal from absolutely nowhere and it gave them momentum. To be out of a cup that we've had good runs in over recent years is disappointing.
"But we stick together as a team, we pick ourselves up, and we go again against Wigan at the weekend. We've got plenty of games coming up and we've got to be ready."
