The stage is set for a monumental European night in Madrid. FC Barcelona, facing a daunting 2-0 deficit from the first leg, travel to the Riyadh Air Metropolitano tomorrow for a UEFA Champions League quarter-final second leg that demands nothing less than a historic comeback against Atletico Madrid.

Manager Hansi Flick has unveiled his squad for this high-stakes mission, and there's a major boost in midfield. Frenkie de Jong, having successfully returned from a hamstring injury over the weekend, is included and could be pivotal in controlling the tempo Barcelona desperately needs.

The squad also sees the return of Gerard Martin, who is fit for selection after an injury scare in the last match. However, defensive options are thinner with young star Pau Cubarsi unavailable due to suspension from his first-leg red card.

Adding to the intrigue, Flick has called upon several academy talents for the trip. Marc Bernal is traveling but awaits final medical clearance on an ankle sprain, while Tommy Marques, Xavi Espart, and Alvaro Cortes also join the group, highlighting the blend of experience and youth Barcelona will rely on for this all-or-nothing clash.
