EPL: Gallagher breaks Crystal Palace hearts to earn Chelsea 2-1 win

Gallagher -- applauded loudly by the home fans in the pre-match warm-up -- received a ball from fellow substitute Christian Pulisic, created a yard of space for himself and then bent the ball around Vicente Guaita for his first Chelsea goal. Earlier, Pierre-Emerick Aubameyang had seized on a headed pass by Thiago Silva to level the match with his first goal for Chelsea in the 38th minute. The Brazilian nodded down towards Aubameyang who let the ball cross him before swivelling and shooting to open his account for the Londoners following his move from Barcelona.

Palace were incensed that referee Chris Kavanagh had given Silva only a yellow card for denying Jordan Ayew a run on goal by handling the ball a few minutes before he set up Aubameyang. Palace defender Nathaniel Clyne was injured as he challenged Silva and manager Patrick Vieira was shown a yellow card for remonstrating with Kavanagh over his decision, backed up by VAR, not to give Silva a red card. Odsonne Edouard had given the Eagles the lead in the seventh minute when the French striker seized on a loose pass by Wesley Fofana, fed Ayew on the right and stabbed home the cross as it came back to him.

The result kept Potter's men eight points adrift of league leaders Arsenal, underscoring the challenge he faces after replacing Thomas Tuchel a month ago, although the Blues have a game in hand over the Gunners. "We had to survive moments as they are a good side with dangerous players. To be a goal down and come away with three points is fantastic, so credit to the players," Potter told the BBC.
