Jese Rodriguez scored the winner on a dream debut as Stoke City downed Arsenal with a controversial 1-0 victory at the bet365 Stadium.
The forward, loaned by Stoke from Paris Saint-Germain, struck early in the second half with an impressive finish as part of a lively performance.
Arsenal were aggrieved when Alexandre Lacazette had an equaliser ruled out for offside in a contentious decision.
And that moment proved decisive as the Gunners were unable to repeat their heroics from last week’s opener against Leicester City to salvage a result.
The two teams now have three points from their first two matches. Arsenal, who were without the injured Alexis Sanchez, have not won their first two games in a Premier League season since 2009 as they suffer an early blow to their title hopes.
