The stage is set for a thrilling Champions League semi-final second leg as Arsenal welcome Atletico Madrid to the Emirates Stadium on Tuesday evening, with both sides locked at 1-1 after a tense first encounter in the Spanish capital.

All eyes will be on two Italian stars who have earned their places in the starting line-ups. Riccardo Calafiori continues his impressive run for Arsenal, keeping his spot after a commanding performance against Fulham in the Premier League over the weekend. The former Roma and Bologna defender came agonizingly close to his first Emirates goal on Saturday, only to be denied by a late VAR review. Having missed four matches across all competitions with a knock before the first leg, Calafiori was an unused substitute in Madrid. Now, he's set to start back-to-back games for the Gunners for the first time since December—a testament to his growing influence in Mikel Arteta's backline.

On the opposite flank, Matteo Ruggeri retains his left-back role for Atletico Madrid. The former Atalanta wing-back has been a mainstay for Diego Simeone's side, starting 12 of their 15 Champions League outings this season. After being rested for Atletico's LaLiga clash against Valencia over the weekend, Ruggeri looks fresh and ready to make an impact. He's joined by another ex-Atalanta star, Ademola Lookman, who also starts, while former Dea goalkeeper Juan Musso is named among the substitutes.

The first leg at the Metropolitano saw both goals come from the penalty spot, with Viktor Gyokeres and Julian Alvarez converting for their respective sides. That leaves everything to play for in North London, where Arsenal will look to leverage home advantage and continue their push for European glory.

Confirmed line-ups:

Arsenal (4-2-3-1): Raya; White, Saliba, Gabriel, Calafiori; Rice, Lewis-Skelly; Saka, Eze, Trossard; Gyokeres.
Subs: Kepa, Setford, Mosquera, Hincapie, Havertz, Odegaard, Norgaard, G. Jesus, Martinelli, Zubimendi, Dowman, Madueke.
