Tickets for Norwich City's Carabao Cup tie against Arsenal next month sold out within hours of them being made available.
The 5,200 tickets allocated to the Canaries for the match against the Premier League giants had gone on sale at 9am yesterday.
But just two-and-a-half hours later, the club's website had a 'sold out' sign for the game.
It is understood there will be further discussions between Norwich City and Arsenal about extra ticket allocation.

'It seems they underestimated the demand drastically,' he said. 'But I am sure they will do everything they can to get more tickets to make sure people don't miss out.
Mr Sainty added: 'We have heard of people going in and buying loads of tickets because their kids support Arsenal. If that is the case, they should be ashamed of themselves.'
Fans who opted to buy their tickets from the Carrow Road office instead of online started queuing from the early hours of Thursday.

Lawrence Osborne said he had arrived at 5am expecting a queue, only to discover he was the only one there.
He said: 'My wife Victoria and I want to take our three children Mackenzie, Lucas and Lochlan to watch the match.'
He said they had told the kids they would try get the tickets, but had not promised them anything.
'It's going to be a surprise for them as they don't know.'
The Carrow Road season ticket holder said City face a tough challenge away at Arsenal.
'They have been playing quite well lately so you would think they have a chance in beating Arsenal.
'I'd rather be at the game than not if it does happen.'
As the first in line, Mr Osborne walked out the ticket office with his five tickets just after 9am. By then the queue had grown considerably.
The match at the Emirates Stadium in London will be played on Tuesday, October 24 after City sealed their place in the last 16 with a 3-1 win at Brentford.
The game will be played two days after the Canaries' trip to Ipswich Town in the Sky Bet Championship, before a home fixture against Derby County.
