Arsenal will be without another key member of their squad for the next month, as Aaron Ramsey is set for a month on the sidelines.

The Welsh midfielder succumbed to a hamstring injury on the hour mark of Arsenal's 4-3 loss to Liverpool on the opening weekend of the Premier League season.

Ramsey joins Per Mertesacker, Danny Welbeck, Gabriel and Jack Wilshere on the injury list, with Mertesacker and Welbeck not scheduled to return until the new year.

Despite Ramsey's injury, the Gunners have received some good personnel news on the eve of their clash with Leicester this weekend.

Laurent Koscielny, Olivier Giroud and Mesut Ozil will all return this weekend after being rested following deep involvements in Euro 2016.
