SUNDERLAND, England, Sept ⁠12 (Reuters) - Arsenal maintained their 100% ⁠start to the season as keeper ‌David Raya saved a penalty and Bruno Guimaraes scored his first goal for the club ​in a 2-0 victory ⁠at Sunderland to ⁠move clear at the top of the Premier ⁠League ‌on Saturday.

Raya rescued Arsenal by pushing Enzo Le Fee's ⁠spot kick against the post in ​the 55th ‌minute and two minutes later summer ⁠signing Guimaraes ​curled the reigning champions ahead.

It was far from a vintage Arsenal display ⁠against a tenacious Sunderland, who ​deserved something for their endeavour, but they dug deep and wrapped it up ⁠late in stoppage time when Bukayo Saka converted a penalty.

Arsenal have 12 points from their opening four games with ​Manchester City, the only ⁠other side not to have dropped ​points, able to join ‌them if they beat ​Manchester United on Sunday.
