Tonight is a massive moment for Italian football in Europe. Two of its clubs, Bologna and Fiorentina, face daunting but thrilling tasks as they attempt to pull off dramatic comebacks in their respective European quarter-final second legs.

Bologna, under Vincenzo Italiano, travel to the intimidating Villa Park to face Aston Villa in the Europa League. The mountain to climb is steep, as they trail 3-1 from the first leg. It will require a near-perfect performance and immense courage to upset Unai Emery's side on their home turf.

The challenge for Fiorentina is even greater. After a heavy 3-0 defeat at Selhurst Park, Paolo Vanoli's men must produce a historic turnaround against Crystal Palace in the Conference League at the Stadio Artemio Franchi. It's a classic 'all or nothing' European night in Florence.

Both managers have emphasized belief and courage in their pre-match comments. Italiano stated his team is "absolutely determined to make things difficult" for Villa, hoping his players can find "something extra." Vanoli was equally defiant, insisting his Fiorentina squad "absolutely" believes in the possibility of a comeback, highlighting the need for a perfect game and a roaring home crowd.

The stage is set for a tense and exciting evening. Here are the official line-ups for these crucial clashes:
