Arsenal reignited their bid for a top-four finish by stunning Chelsea at Stamford Bridge, with Eddie Nketiah scoring twice against a shaky Blues defence.
Nketiah capitalised on a defensive error to give the visitors the lead, reopening the debate over his Arsenal future in the process. However, Timo Werner delivered a quickfire equaliser - albeit via a big deflection - after a loose pass from the Gunners striker gave possession to the Blues.
The hosts weren't level for all that long, though, with Emile Smith Rowe restoring Arsenal's lead with an smart finish which caught out Edouard Mendy in the Chelsea goal. Still, not to be outdone, Chelsea made it 2-2 within minutes through Cesar Azpilicueta.
