Arsenal are set to learn the full extent of the thigh injury suffered by defender Gabriel while on international duty, amid growing concern he could be sidelined for several weeks.

The centre-back limped off in visible discomfort during Brazil’s friendly against Senegal at the Emirates Stadium over the weekend and has since returned to London for treatment.

Early indications suggest the 27-year-old could miss at least four weeks, with some sources warning his absence may extend into January. The exact severity and recovery timeline will be confirmed after further medical assessments in the coming days.

Gabriel’s unavailability for Sunday’s Premier League clash against rivals Tottenham is a significant setback for Mikel Arteta. The Brazilian has forged a rock-solid defensive partnership with William Saliba, anchoring a back line that has conceded only five league goals this season.

Piero Hincapié and Cristhian Mosquera are the leading options to step in should Gabriel be ruled out.
Despite sitting top of the Premier League, Arsenal’s campaign has been hit by injuries to several key players.

Martin Ødegaard, Noni Madueke, Gabriel Martinelli, Kai Havertz, and Viktor Gyökeres are all currently sidelined, though each is expected to return soon after varying spells out. It remains unclear whether any will be fit in time for the north London derby.
