Guimarães and Saka fire Arsenal to win at Sunderland after Raya spot-kick save

As the final whistle blew Bruno Guimãraes wore a mischievous smile, Enzo Le Fée was a study in dejection and Arsenal’s immaculate start to the season remained unblemished. Two minutes after David Raya had, rather majestically, saved Le Fée’s second half penalty, Guimãraes delighted both his new north London, public and plenty of old friends in Newcastle by sending a shot curving past Robin Roefs.
