Leicester manager Craig Levein paid tribute to his team's character after they came from two goals down to defeat in-form Tottenham in the FA Cup.
"We have played well in a lot of games without getting a result," said Levein.
"We were disciplined and showed great belief and have sent the supporters home with a big smile on their faces."
Levein said he hoped the shock victory would prove a real boost for his struggling team, who are currently fourth bottom in the Championship.
"Things have been difficult but a lot of building blocks are in place," he added.
"There were a lot of young players out there against Spurs and they are making their way in the game.
"It gives me a great boost personally because it shows we are heading in the right direction and it lets the players know that we are capable of this sort of performance."
Tottenham boss Martin Jol urged his players to focus on their Premiership after the surprise defeat.
"We now have to concentrate on the league," said Jol. "All credit to Leicester - they never gave up.
"I thought we played well in the first-half and cannot remember Paul Robinson having to make a save.
"But the goal before the break gave them a lifeline and we did not do enough in the second-half.
"Even after it was 2-2 I did not think it was a problem but if you give away a goal in the last few minutes then you give yourself a real problem."
