Arsenal are staring down a potential defensive crisis just as they prepare for the biggest match of their season—the Champions League final against Paris Saint-Germain. With key full-backs Ben White and Jurrien Timber both battling injuries, manager Mikel Arteta faces a tough call on who will slot in at right-back for this high-stakes showdown.

All eyes are turning to Cristhian Mosquera, a natural center-back who can also play on the right side of defense. While versatile, the young defender would be stepping into the spotlight on one of the biggest nights in the club's recent history. And standing in his way? None other than PSG's electrifying winger, Khvicha Kvaratskhelia.

Kvaratskhelia has been a revelation this Champions League campaign, dazzling fans and defenders alike with his blistering pace, sharp intelligence, and technical brilliance. The Georgian star is widely considered one of the most dangerous attacking players in world football right now, and he's expected to be the focal point of PSG's attack in the final. For Mosquera, it would be a baptism by fire—a one-on-one battle against a player at the very top of his game.

Former Liverpool midfielder Danny Murphy weighed in on the dilemma, admitting the thought of Mosquera facing Kvaratskhelia is nerve-wracking. "He's the best winger in the world right now," Murphy said. "Mosquera is a defender—he's a centre-half, he's quick, and he can play right-back. He can sit in position and have a one-vs-one battle. It's not the end of the world, but it's not ideal."

There's also chatter about deploying midfield anchor Declan Rice at right-back for extra defensive solidity. But for now, Mosquera appears to be the more natural fit for the role—even if his top-level European experience is limited. Arteta now faces a defining decision: trust the young defender on the grandest stage, or reshuffle the lineup in search of safety. Either way, Arsenal fans will be holding their breath.
