Colchester United have defeated Champions' League Finalists Tottenham Hotspur to progress to Round Four of the Carabao Cup.
As in the previous round, this match went to penalties - and again the U's were victorious.
The game itself ended goalless, then the U's won 4-3 as Christian Eriksen and Lucas Moura failed from the spot.
Dean Gerken saved Eriksen's effort, Moura hit the crossbar, and Tom Lapslie drilled home the decisive spot kick for the win.
In the early stages, the Premier League side dominated possession, but the U's kept a disciplined shape and protected Gerken from clear cut chances in the early stages.
In fact, it took Spurs until the fourteenth minute to get a shot away - Troy Parrott having his effort deflected wide after a Dele Alli backheel.
Moura shot over and Alli wide but still Gerken hadn't been troubled as the game ticked over the half hour mark.
Gerken then had to make what was to be his only meaningful save, palming away a free kick.
The game was goalless at the break, and U's Head Coach had to make an enforced change just five minutes into the second half.
Ryan Jackson pulled up with a hamstring injury and had to be replaced by Paris Cowan-Hall.
The U's were still defending in numbers, and Parrott had further efforts blocked and another over the bar.
The closest the visitors came to scoring came when Kyle Walker-Peters hit the post with an angled shot on fifty six minutes.
Mauricio Pochettino then decided he needed some reinforcements just after the hour, and bought on Son and Eriksen, then Lamela a few minutes later.
John McGreal reacted by sending on Javani Brown and Luke Norris, to give the U's some attacking inpetus.
And the U's had their best spell of the game in the final fifteen minutes.
Senior got clear on the right, but just failed to find Norris, and then Cowan-Hall shot wide after advancing from his right back position.
Dangerman Senior, who looked like he had a late second wind, drove forward with the ball on eighty eight minutes, but just missed the target with his shot from the edge of the box.
The four minutes of injury time went by without incident, and the game went to penalties.
Dean Gerken dived full leangth to save Eriksen's opening effort, before Luke Norris put the U's one up.
Alli, Frank Nouble and Lamela all scored, before Brown's chip was easily saved by Gazzaniga to level things up.
Son and Cowan-Hall both netted and it was 3-3 going into the fifth penalty for either side.
Moura decided to go high, but his effort was too high and rebounded out after crashing against the crossbar.
Academy product Tom Lapslie was the man to take the fifth for the U's, and calmly struck his effort low to the keeper's right and into the bottom corner.
Cue jubilant scenes at the JobServe Community Stadium, and thoughts of another big night in the Fourth Round of the Carabao Cup.
The draw will be made following the MK Dons Vs Liverpool clash on Wednesday evening.
