If Gabriel is set for a spell out of the team, he will be sorely missed by Arsenal as they try and win their first Premier League title since 2004. The Brazilian has improved a great deal in the last couple of seasons, forming a formidable partnership with fellow centre-back William Saliba. But the Gunners have proven to be rock solid at the back, even with Saliba being out injured earlier this season. The likes of Cristhian Mosquera have come in and looked very assured in defence, and they also have Ben White, Riccardo Calafiori and Piero Hincapie as backups. But his absence is undoubtedly a blow.
