Arsenal do score relatively highly, however, on soft-tissue injuries and have suffered with a particular concentration of injuries to key players. They are likely to be without four of Arsene Wenger’s 10 preferred outfield starters (Alexis Sanchez, Francis Coquelin, Santi Cazorla and Theo Walcott) against Sunderland on Saturday, although Walcott has a chance of returning. Arsenal still hope Sanchez could return for the Premier League match against Manchester City on Dec 21 but he and Cazorla will definitely miss the Champions League decider against Olympiakos next Wednesday.
