Swindon boss Paolo Di Canio was bursting with pride after watching his side pull off a shock 4-3 extra-time victory at Stoke to book a place in the Capital One Cup third round.
The npower League One team stunned their Barclays Premier League hosts by taking a 2-0 lead in the first half at the Britannia Stadium thanks to a brace from James Collins. Stoke rallied after the break as goals from Kenwyne Jones and Jon Walters took the contest into extra-time, but Swindon would not be denied as Aden Flint put them 3-2 ahead before Collins responded to Peter Crouch's equaliser by completing his hat-trick with a minute remaining.
"It is obvious that when you win against a side like Stoke City away from home - in a place where teams like Arsenal and Manchester United find it difficult to score even one goal and you are playing in a fortress - it is something special," the Italian said.
"We scored four goals and I don't want to exaggerate, but I think we created another five or six clear chances to score.
"I don't think they underestimated us and all the congratulations I received from (Stoke manager) Tony Pulis at the end of the game was special for me because he is an experienced and very good manager who has achieved fantastic things with Stoke.
"So I am very proud. It is only one match, but to win 4-3 away from home against Stoke City is a special moment for my club, and I think one of the best performances in this club's history."
Stoke finished the match with 10 men after summer signing Jamie Ness, having come on as a 77th-minute substitute to make his debut, was forced off during extra-time with a groin problem which Pulis said afterwards he was "a little bit concerned" about.
Pulis - who has also recruited Geoff Cameron and Michael Kightly this summer - is looking to strengthen his squad further before Friday's transfer deadline.
He said: "The next couple of days will determine what we bring in, who we can bring in and everything else. We have about three or four ongoing at the moment.
"We need a couple, we need to freshen it up as I've said. But we also need to move one or two on, and that is important."
