Jorginho was left red-faced on Wednesday night after the Chelsea midfield maestro miscued a back pass to Kepa Arrizabalaga, leading to Arsenal's opening goal at Stamford Bridge.
The Italian, 29, was selected by Thomas Tuchel as Chelsea sought to make it eight games without defeat as Mikel Arteta's Gunners arrived in west London looking to finish the season with a flourish after a poor campaign.
However, the midfielder got it all wrong midway through the first half, misdirecting a pass to goalkeeper Kepa that was directed towards his own goal with the Spaniard some distance from the ball.
