Brighton manager Roberto De Zerbi praised his squad's spirit and versatility as they beat Manchester United.
The Albion managed an impressive 1-0 win over the Red Devils thanks to a late Alexis Mac Allister penalty.
United had the better of the first half, but Brighon took control and created numerous chances in the second period.
We deserved to win today and in the semi-final," said the Italian to reporters post-game.
If you play well there might be one time when you can lose but most of the time, from my experience in football, you win.
We played well and had a lot of chances but the clean sheet was also important."
He added on Moises Caicedo filling in defensively: We have reached a level with the right players in the right positions and I didn't want to change.
Caicedo is a top, top player who can play anywhere and [Billy] Gilmour deserved to play after his performance against Wolverhampton, he was fantastic. They both showed their quality."
