Arsenal have been dealt a fresh blow ahead of the visit of Liverpool on Sunday as midfielder Santi Cazorla is ruled out through illness.Cazorla has made 20 Premier League appearances for the Gunners this season, scoring four and assisting a further three, but will not be available for selection as the north London side look to avenge their embarrassing 5-1 defeat at Anfield last weekend.googletag.cmd.push(function() { googletag.display(“div-gpt-ad-1389116196215-0”); });The midfielder missed just over a month of action earlier this season through an ankle injury, just as Mesut Ozil was brought into the side following a 42.5 million club-record transfer – meaning that Cazorla did not play alongside the German until October 19, in a 4-1 win over Norwich City.Cazorla will likely be replaced in the starting line-up by Mathieu Flamini, who returns after serving a three-match suspension following his red card against Southampton at the end of January.
