Mikel Arteta is facing a selection headache ahead of Arsenal's high-stakes London derby against Chelsea this weekend. The Gunners boss saw two key first-team players absent from Thursday's preparations as the squad gear up for the Emirates clash.
Gabriel Martinelli has officially ended his seven-year association with Arsenal, completing a blockbuster £60m move to Saudi Pro League giants Al-Hilal. The Brazilian forward, who was a pivotal figure in the Gunners' recent Premier League title success, makes the switch after being frozen out of the first-team picture by Mikel Arteta at the start of the new campaign.
