Atletico Madrid will face Barcelona in the second leg of their Champions League quarter-final on Tuesday night at 21:00 CEST, holding a 2-0 advantage from the first leg. Diego Simeone appears confident in his starting XI, likely replacing the suspended Marc Pubill with Clement Lenglet due to David Hancko's injury. Meanwhile, Hansi Flick's Barcelona is grappling with several uncertainties, including injuries to key players like Andreas Christensen and Raphinha, as well as the suspension of Pau Cubarsi. Despite these challenges, Flick remains optimistic about his team's chances. Gavi and Frenkie de Jong are set to start, while Marc Bernal's fitness is still in question. Both teams have multiple players one booking away from missing the potential semi-final, adding extra tension to the match.
