Arsene Wenger revealed Arsenal would go as far as stopping players shaking hands if it meant keeping a virus from spreading through the squad.
The Gunners hope to have Per Mertesacker available for Saturday evening's trip to West Ham after the German missed the midweek Champions League win over Olympiakos with a flu-like illness which had also previously laid low England forward Theo Walcott, midfielder Francis Coquelin and captain Thomas Vermaelen.
While the current outbreak is nothing like an epidemic, Wenger maintains the club are always cautious in regards to prevention, and he said: "We have improved the level of hygiene in the dressing room, we clean everything. It is funny, but shaking hands is one of the biggest things to spread virus."
