Santiago Mouriño

Key strength: Pace and recovery

Overlapping full-back

Sitting 4th in La Liga with a roller-coaster LWWLW rhythm, Atlético de Madrid have navigated a season of wild oscillations at the Metropolitano. Through this turbulence, one unlikely figure has emerged as Diego Simeone's most trusted lieutenant: Santiago Mouriño, the 24-year-old Uruguayan right-back wearing number 15. The Montevideo native has racked up an impressive 2,479 minutes across 29 appearances, establishing himself as Simeone's preferred outlet on the right flank. While his modest return of 1 goal and 2 assists won't dominate highlight reels, his true value lies elsewhere: the tireless overlapping runs, defensive solidity with 70-rated defending, and that feisty competitive edge captured by 8 yellow cards. At €20 million, Mouriño embodies the shrewd South American recruitment that has long defined Atlético's identity. As they chase Champions League qualification, the Uruguayan isn't merely filling a squad role—he's building a compelling case as the long-term solution at right-back, one lung-busting overlap at a time.
