Arsenal stretched their perfect start to the Premier League season to four wins from four, defeating Sunderland 2-0 at the Stadium of Light on Saturday — with Bruno Guimarães and Bukayo Saka both finding the net.

Guimarães marked his first goal for Arsenal with a stunning strike, the former Newcastle United midfielder announcing himself emphatically at his new club. Saka then made the result safe in stoppage time, converting from the spot in the 97th minute after Reinildo was dismissed for a foul on the England winger — his second booking of the match.

Raya's penalty save proves pivotal

The afternoon had not been straightforward for the Gunners. In the 55th minute, defender Ezri Konsa was penalised for pulling down Dan Ballard inside the box, handing Sunderland an opportunity to level. However, goalkeeper David Raya read Enzo le Fee's effort superbly, diving low to his left to keep the scoresheet clean.

Jurrien Timber, back in the Arsenal lineup after injury, thought he had doubled the lead with a powerful header from Martin Odegaard's free kick, but the goal was ruled out for offside — a bitter blow for the returning defender.

Gunners three points clear at the top

The victory keeps Arsenal three points above Manchester City, who travel to Manchester United on Sunday, and extends manager Mikel Arteta's side to six wins from six across all competitions this season.

For Sunderland, it was a frustrating afternoon at home. The hosts remain 14th in the table on four points, with the penalty miss from le Fee a moment that could loom large in the weeks ahead.

With Saka's clinical finish and Guimarães's debut goal giving Arsenal the platform they needed, Arteta's men look ominous at the summit of the Premier League table.
