WHAT HAPPENED? The Gunners made light work of another London derby date, with a 4-1 victory lifting them eight points clear at the top of the Premier League table. Bukayo Saka – who bagged a brace – Gabriel Martinelli and Granit Xhaka got the goals for Arsenal, but their defensive unit was unable to keep a clean sheet after seeing Saliba and Tomiyasu pick up knocks in the first half of a Europa League last-16 encounter with Sporting on Thursday.
