Luton boss Paul Buckle praised his players after their FA Cup win over Norwich which saw them become the first non-league team since 1989 to knock a Premier League side out of the competition.
"It has not really sunk in yet. It is an incredible performance by the players," he told Sky Sports.
"The most pleasing thing for me was that we defended very well and carried a threat going the other way. I am absolutely delighted. The fans were out of this world. We probably could not have done it without the 4,000 travelling supporters."
Before the Norwich win, Luton had another shock victory after they knocked Wolves out in the third round and Buckle believes that his side were buoyed by that performance.
He explained: "We took great strength from the Wolves game. It is not so long ago Wolves were in the Premier League.
"We stuck to the same plan. It is a lot easier to work in a structure. At our level, no disrespect, there is not an awful lot of structure to the game at times and it is more of a fight."
