Norwich City goalkeeper Mark Bunn admitted he is in technology's debt last night after his dramatic late penalty save helped the Canaries secure a quarter-final tie against Paul Lambert's Aston Villa in the Capital One Cup.

City had produced a memorable comeback as a Jan Vertonghen own goal and a Simeon Jackson strike cancelled out Gareth Bale's opener for Tottenham.

But the drama wasn't over as Marc Tierney was adjudged to have fouled Kyle Walker inside the penalty area. Clint Dempsey looked all set to force extra-time but the USA international had not counted on Bunn researching his penalty technique on an iPad yesterday afternoon.

'Before the game we study penalties and luckily enough before the game I saw his penalty and he went the same way,' said the 27-year-old, who arrived from Blackburn in the summer. 'One of the lads has got an iPad so I watched about three or four on there. He had about two or three penalties with his previous club and he went the same way every time. Luckily enough he went that way again.'

Boyhood Spurs fan Bunn admitted his magic moment was made all the sweeter by his family being in the crowd.

'I'm just so happy to get the win because I supported Totttenham growing up – I had all my family here today so it was fantastic. I thought Bale would take it but we had studied all the penalties before and I was just glad to get in the way. I took my time – I took as long as possible and luckily enough I went the right way.'

Just when the drama appeared to be over upon the final whistle, news filtered through that City would face Aston Villa in the last eight of the competition.

The prospect of getting one over the previous boss, Lambert, will ensure a full house at Carrow Road but Bunn hopes it is merely another step on the road to Wembley.

'Everyone wants to get to Wembley and we've got a great opportunity now – hopefully we can get there,' he added. 'I'd love to stay in the team for that. I will just keep working hard on the training pitch and keep doing what I'm doing.'

Chris Hughton's substitutions won the day for his side as Tettey, Jackson and Grant Holt all played major roles in the comeback.

'They (Spurs) are a fantastic team and I knew that I would be quite busy today,' added Bunn. 'The lads played brilliantly today – we dug in deep and we kept going and in the end we got the win.

'We've got a great squad of players and they came on and made a difference. It was an all-round great team performance – we dug deep. We're just looking forward to the next round now.'

Upon his arrival at Carrow Road, Bunn knew he would have to play second fiddle to John Ruddy but he hopes his performances can push the England international.

'John is a fantastic keeper – we all know that. We're just going to keep working hard on the training pitch and when I get the chance I've got to take it.

'I love it here – the fans are fantastic, hopefully I can show them what I can do and push to get in the team. It's a great team and I think we will only get stronger. I think it's a matter of time before we push up that league. We've got to look to Saturday and get another good performance in the league.'
