Bukayo Saka has provided Arsenal with a welcome boost after returning to training ahead of their clash with Chelsea on Sunday.
The winger has been a crucial figure for the Gunners so far this term, scoring the winner in their success over Liverpool last month, and will be available for the trip across London to Stamford Bridge. The clash in west London is the first of three games in six days for the league leaders.
Mikel Arteta's side have surpassed all expectations by setting the pace in the Premier League and will hope to go into the World Cup break still leading the pack. Arsenal face Brighton and Hove Albion in the Carabao Cup next Wednesday before taking on Wolves a week on Saturday.
