After victory at Arsenal last night, the Welshman told Sky Sports News: "It is very special. It is the biggest game you can play in at club level and all the lads are buzzing, especially after the performance tonight.
"There was some great play and to do that against a very good Arsenal side was brilliant."
Darren Fletcher will play no part in the Rome showpiece after being sent off for a challenge on Cesc Fabregas.
Giggs added: "To miss a final is tragic. He has had such a good season and played so well tonight, all the lads are gutted."
"Whoever we play it is going to be tough and we need to play like we did tonight," he said.
