City duo out of Gunners clash
David Silva and Mario Balotelli have been ruled out of Manchester City's crucial Premier League encounter with Arsenal.
The pair have failed to recover from their respective knee injuries, leaving manager Roberto Mancini to consider his options for the trip to north London.
City have not beaten the Gunners away from home since 1975 but know victory this time would open a five-point gap on Arsene Wenger's men.
