Arsenal will study UEFA's justification for handing Eduardo a two-match European ban for diving before deciding whether to appeal against the verdict. European football's governing body opened disciplinary proceedings against the Croatia international for “deceiving the referee” after he tumbled theatrically to win a penalty in last week's Champions League play-off against Celtic. Despite there appearing to be no contact with Celtic goalkeeper Artur Boruc, referee Manuel Mejuto Gonzalez awarded the spot-kick, which Eduardo converted himself to set Arsenal on its way to a comprehensive 3-1 win and into the lucrative group stages. The dive caused a storm of controversy and UEFA took action against Eduardo Tuesday. Arsenal is understood to have made a 19-page submission to UEFA ahead of the hearing, which clearly made little impact on the panel. The Gunners have three days to lodge an appeal against the suspension which, if upheld, would rule Eduardo out of the Champions League group matches away at Standard Liege on Sept. 16 and at home to Olympiacos on Sept. 29. “The club is disappointed with UEFA's decision to suspend Eduardo for two Champions League matches starting with Standard Liege on Sept. 16,” a statement from Arsenal read. Cole stays with Chelsea Chelsea defender Ashley Cole signed a new four-year contract with the Premier League club Wednesday. Cole is the second Chelsea star to commit his future to Carlo Ancelotti's team recently after captain John Terry put pen to paper on an improved five-year deal Monday. Cole joined the Blues in a controversial move from London rival Arsenal in 2006 and remains arguably the best full-back in the Premier League. Ranieri takes charge AS Roma needs a “jolt” to snap out of its early season funk and return to its place as a Serie A contender, Claudio Ranieri said Wednesday at his introduction as the club's coach. Ranieri agreed to a two-year contract Tuesday after Luciano Spalletti resigned following two losses to open the Italian season. “Spalletti's Roma had a sparkling sense of play. My philosophy is a little different – I'm bringing my pragmatism to this team,” Ranieri said.
