Nottingham Forest progressed from their Europa League quarter-final with a 2-1 aggregate win over Porto to book a last-four meeting with Aston Villa.
The first leg of the all-Premier League semi-final will take place on April 30 at the City Ground with the return leg at Villa Park on May 7. The winners will play Freiburg or Braga in the final on May 20.
After battling to a difficult 1-1 first-leg draw in Portugal, Forest were far more assured on home turf, buoyed by an early Jan Bednarek dismissal for a reckless challenge on Chris Wood that led to the striker hobbling off with yet another knee injury.
Porto, down to 10, were unable to match Forest's intensity as Morgan Gibbs-White capitalised on the player advantage shortly after by striking via a deflection off Pablo Rosario. He celebrated by dedicating the goal to missing midfielder Elliot Anderson, granted compassionate leave following the death of his mother.
Vitor Pereira had promised his side were out to show intent and ambition in a competition they had failed to appear in for nearly 30 years before this season, and now they must negotiate their toughest obstacle yet: Unai Emery's Villa. Their Premier League counterparts dismantled Italian outfit Bologna .
Forest were convincing winners for the majority despite making hard work of the second period, with William Gomes delivering a scare when crashing a strike off the woodwork and Alan Varela doing the same late on. But now Pereira's charges must balance their European hopes with the business end of a difficult domestic season, still not completely clear of relegation trouble.
They host Burnley live on Your Site on Sunday; a game with arguably even greater consequence in the fight to stay a top-flight club. Murillo and Callum Hudson-Odoi were lost to injury before the night was out and Pereira will hope that does not derail their six-game run-in. His job surely depends on it.
Analysis by Your Site' Laura Hunter:
Balancing survival with chasing silverware will surely be the ultimate determination of Vitor Pereira's longevity at Nottingham Forest. Get it right and he could go down in history. But weight the emphasis too heavily in one direction and the consequences could be disastrous.
It's hard to know where to go from here. Forest have not been in a major European semi-final since 1984. This will mean a lot to a club with rich tradition in European competition - having been starved of the privilege for such a long time. Match-winner Gibbs-White described it as one of his most memorable nights at the City Ground.
And yet, such an achievement will be rendered meaningless if Premier League survival is compromised. The balance must be right, especially with winnable games against Burnley and Sunderland up next. Where do alternating priorities shift now?
Nottingham Forest boss Vitor Pereira to TNT Sports:
"I have a fantastic team. It is not about the manager. It is about the team because they have the true spirit and the character. They deserve it, as do the supporters.
"The faces on the other bench are faces that I recognise. It is normal they have fire at the end. We need to suffer together and we need to feel proud of ourselves and the supporters."
On facing Burnley: "We start preparing in the dressing room now.
"After the game we discuss. We have a few minutes to celebrate but then it's time to recover. We prefer to go in with a win because the motivation is different. We need to fight and get the three points."
