The defender refused to criticise Maicosuel after the attacking-midfielder's missed 'Panenka' penalty meant the Serie A side will have to settle for a spot in the Europa League
The Brazilian missed a 'Panenka' penalty during the shoot-out which proved to be the only spot-kick not to find the net as the Italians lost 5-4.
The failed attempt may well have cost the Zebretti a spot in the Champions League this season but Domizzi argued that his side were already culpable of numerous errors.
"Paradoxically, we made two mistakes near the end with Pablo Armero and someone else that were even worse than missing a penalty," he said to reporters after the game.
"Whether you chip it, force a save or miss completely in a shoot-out, nothing changes.
"There is so much bitterness. It’s a shame to a certain degree, as it was clear that technically at this level we struggle.
"We were in it while we had energy in the legs, but at the end of the day we ran out of steam. All of us gave our last drop of sweat for this, but unfortunately Braga were better."
“We knew it was tough and there’s no point hiding that this is even more painful than last year. Repeating a season like that is pretty much impossible, so just finishing top six would be great. That’s the bread and butter for a club like Udinese.”
A dejected Guidolin echoed the sentiments of his player and declared that he would have to reflect on the result, leaving his future at the club uncertain.
"This is causing us enormous pain. Evidently I am not capable of leading a team into the Champions League. When you get so close several times and can’t go through, you have to learn from that experience and accept the truth," he told Sky Sport Italia.
"Unfortunately we were incapable of giving more and the coach has to take responsibility, because a team like Udinese ought to play better. I blame the coach, as the team should’ve been more prepared for this play-off.
"I am going home now to hopefully rest and reflect on the situation. That is all."
The trainer was asked whether this meant he was to debate his role at the club going forward but the 56-year-old refused to answer and walked away from the reporter.
