Arsenal silenced some critics on Saturday as they convincingly beat Bournemouth 3-0 at the Emirates Stadium, thanks in part to a brace from Danny Welbeck.
However it was not all positive for the Gunners as Francis Coquelin went off injured mid-way through the second half.

The Frenchman limped off on 80 minutes, less than 15 minutes after coming on during the 3-0 victory.
Despite having used all three of their substitutes, Arsenal were able to see out the game with ten men, without conceding a goal.
Coquelin is known to be prone to an injury or two and has often had issues with his hamstrings and knees especially, over the past few seasons.
