Arsenal appear braced for a significant setback as star centre-back Gabriel Magalhães faces a potentially lengthy spell out through injury.The 27-year-old has been one of Mikel Arteta’s most indispensable players in recent seasons, forming the backbone of a defensive unit that has transformed the Gunners into consistent Premier League title challengers.His combination of aerial dominance, physicality and leadership, alongside his growing threat from attacking set pieces, has made him a crucial figure at both ends of the pitch.But Arsenal’s defensive stability is now under threat following Gabriel’s premature withdrawal during Brazil’s 2–0 victory over Senegal at the Emirates Stadium last weekend.Arsenal suffer Gabriel setback at crucial stageThe centre-back was forced off just after the hour mark, clutching his right thigh, and was immediately released from the national team squad.His departure raised concerns within the Brazil camp and even more so among Arsenal supporters already anxious about their team’s growing injury list.According to The Athletic, further medical examinations are scheduled, but early indications suggest Gabriel may be facing up to two months on the sidelines.If confirmed, the defender would be ruled out until mid-January, missing a crucial run of fixtures during the congested winter period.A best-case scenario indicates a recovery time closer to four weeks, which could enable him to return just before Christmas, though Arsenal are said to be preparing for the longer prognosis.The timing could hardly be worse. Gabriel now joins a lengthy injury list at Arsenal, one that already included Martin Ødegaard, Viktor Gyökeres, Kai Havertz, Gabriel Martinelli, Noni Madueke and Gabriel Jesus prior to the international break.More Stories / Latest NewsMan United target move for Premier League centre-back as Harry Maguire replacmentNov 19 2025, 6:23Heartbreak for Arsenal as extent of Gabriel’s injury is revealedNov 19 2025, 6:19Unsettled star puts Man United contract talks on hold to pursue transfer awayNov 19 2025, 6:17Mikel Arteta has worthy replacements in his squadArsenal centre-back Gabriel Magalhaes in action (Photo by Alex Pantling/Getty Images)Arteta, who has worked tirelessly to build depth and balance across the squad, is now facing the prospect of navigating multiple competitions without several of his most influential players.With the festive schedule approaching, Arsenal’s reliance on defensive pairing William Saliba and Cristhian Mosquera will grow.
