The hosts made their intent clear early. Despite a bright opening from Bologna, including a sharp effort from Federico Bernardeschi that forced a save from Emiliano Martinez, Villa quickly took control.

It was Ollie Watkins who set the tone, calmly finishing from close range after clever work by Morgan Rogers and Emiliano Buendia. The goal marked Watkins' 100th for the club, a milestone his manager later described as "a special day".

Villa's attacking rhythm never faded. Although Federico Ravaglia saved a Rogers penalty midway through the first half, the home side responded instantly. Buendia reacted quickest from a throw-in, controlling brilliantly before finishing at the near post.

Rogers then got his reward before the break, drilling home Villa's third to end his recent goal drought and effectively end the contest. From there, Unai Emery's side controlled the match with authority.

The fourth goal arrived in the second half when Ezri Konsa produced a fine turning volley, capping another commanding European night at home. The result also extended Villa's remarkable run of nine straight home wins in major European competition.

After the match, Emery praised both the performance and his players' mentality. "We played a serious match," he said. "We respected them and the competition, but we were ruthless in the final third. That made the difference."

Looking ahead, Villa will face Nottingham Forest in an all-English semi-final after they defeated Porto. Managed by Vitor Pereira, Forest represent a familiar and dangerous opponent.

"It's going to be very special," Emery said. "Both clubs have history in Europe, and to play a semi-final like this is very important. We are enjoying the journey, but we know how difficult it will be."

Emery also highlighted Watkins' contribution, adding: "We need him scoring goals. Today was his day, but we also need goals from players like Buendia, Rogers and Konsa."

Villa now head into the semi-finals full of confidence, with momentum building at exactly the right time.
