Theo Walcott scored twice as 10-man Arsenal won their sixth Premier League game in a row, despite a spirited Swansea City display in Bob Bradley's first match as manager. Gunners and England forward Walcott now has five goals in eight games, taking advantage of a heavy Jordi Amat touch for his first and a poor Jack Cork header for his second. The Swans looked dejected after the quick-fire double, though Gylfi Sigurdsson pounced on a Granit Xhaka error to curl in and give them hope before the break. Walcott's late misses were among 16 Arsenal shots - but Swansea managed 13 themselves.
