Ronald Koeman: Injury cost Southampton at Arsenal

Southampton boss Ronald Koeman says an "unlucky" injury to Toby Alderweireld was costly in his side's 1-0 defeat by Arsenal.

Saints keeper Fraser Forster has frustrated the Gunners with a string of fine saves, but Alexis Sanchez broke the deadlock two minutes from time after Alderweireld left the field injured with all three of Koeman's substitutions already made.

Southampton remain third in the Premier League, but are now winless in their last three matches.
