The San Mames showdown is a huge occasion and opportunity for the Reds, and there was a welcome boost with Diogo Dalot, Leny Yoro and Joshua Zirkzee named in a 26-man travelling squad, after training at Carrington on Tuesday morning.
Matthijs de Ligt was not in the squad but has come out to the Basque Country to support his colleagues, as he did an individual session at our base earllier.
Lisandro Martinez is the only other first-teamer sidelined, with Jonny Evans also fit enough to be in contention.
When it was suggested Zirkzee's inclusion was not expected by anybody, after he had initially been ruled out for the season when going off injured at Newcastle United, Amorim said: "Me neither! So they recover quite well. They push, of course, and we have to respect the feeling of the player but we push a little bit, as they wanted to be part of the team. That is a very good sign.
"Very good for us. Of course, they are limited in the minutes for the game but they can help us win the game. De Ligt is out."
At the end of the press conference, the boss was asked if the prospect of extra-time and penalties would influence his team selection.
"No," he replied. "I just think of the best starting XI to start the game. Then it's really important to have options on the bench, to change the game. Sometimes, they are really, really important to win a final. I'm not thinking about going to extra-time. Of course, we have that possibility but I never think about that.
"Maybe, in the final minutes, if we have two subs, then one and can wait for extra-time to have a think about the possibility. But, in the beginning of the game, I just want to win the game really fast.
"We know and we proved against Lyon, if we have to score three goals in six minutes we are able to do it, especially with our fans in the stadium!"
