London, Sept. 1: Conor Gallagher's sublime last-minute strike earned Chelsea a 2-1 win against his former club Crystal Palace to give Graham Potter a winning start in the Premier League.
Second-half substitute Gallagher, who spent last season on loan at Selhurst Park, curled home in the 90th minute to win a game that Chelsea trailed early on.
Odsonne Edouard had given Palace the lead on home soil in Saturday's contest, only for Pierre-Emerick Aubameyang to net his first goal for Chelsea before half-time.
Palace felt Thiago Silva should have been sent off before assisting that Aubameyang equaliser, and their mood was not helped by former player Gallagher's late winner.
Wesley Fofana was drafted back into Chelsea's line-up but gave the ball away and then failed to cut out a cross that was clinically converted by Edouard inside seven minutes.
Last man Silva was fortunate to stay on the field when using his hand to stop Jordan Ayew from running through on goal, referee Chris Kavanagh electing to issue only a yellow.
To rub salt in the Palace wounds, Silva nodded down a long ball into the path of Aubameyang, who let it bounce across his body and half-volleyed into the bottom left-corner.
Just when the sides appeared to be heading for a first league draw in 23 meetings, Gallagher – on the field for just 14 minutes – found the top-right corner from range to snatch the win.
