Arsenal defender a doubt for Chelsea game

Arsenal centre-back Per Mertesacker is a doubt for Saturday’s game against Chelsea.

The German has missed the last four games because of illness and manager Arsene Wenger said the defender “may be short” for the match at Stamford Bridge.

But midfielder Aaron Ramsey is expected to return to the side after missing the away midweek Champions League defeat against Dinamo Zagreb on Wednesday.

Wenger’s team have not beaten Chelsea in 13 league meetings, but won 1-0 when the sides met in this season’s Community Shield.
