Asked about his team's achievement, Poyet said: "It is very difficult to explain.
"I don't remember another game like this one, being involved as a player or anything.
"Why? Because normally, when you score in the last minute or so you don't expect to then concede within one or two minutes, and then if you miss the first two penalties, you don't expect to win the game either.
"So how we did it? I think we need to ask Vito Mannone - I think he can personally answer that because he has been getting better and better and today he was the difference between the two teams."
He added: "When Vito got into the dressing room, the whole squad and staff started singing his name and there is no better feeling for a football player.
"He was half happy, half embarrassed. It was a special night for him."
