Arsenal's slight edge as trader consensus favorite at 39% implied probability reflects their strong Champions League run, including advancement past Sporting CP and a prior group-stage win over Atlético Madrid, but mounting injury concerns have kept the semi-final first leg tight ahead of April 29 at Riyadh Air Metropolitano. Key Gunners absences or doubts—Bukayo Saka (Achilles), Martin Ødegaard (knee), Jurrien Timber (ankle), Riccardo Calafiori (undisclosed), and Declan Rice (fitness test)—severely test squad depth on Atlético's home turf, where Diego Simeone's compact defense and counter-attacks thrive. Atlético face their own issues with Nahuel Molina (calf) and José Giménez (muscle) sidelined, fueling the razor-thin 35% for the hosts and 28.5% draw pricing amid evenly matched form.
