Jeers ring around Selhurst Park as Chelsea make it 13 straight wins against Palace in the Premier League with a 3-1 comeback triumph.
Pochettino’s side were woeful in the first half, sloppy in possession and eventually punished when Lerma rocketed in his 30th-minute opener that was also his first goal for the club.
Sending on Nkunku at the break, the Blues immediately responded as former Eagles loanee Gallagher swept home from Gusto’s right-wing centre.
This London derby seemed destined for a point apiece as the game wore on, only for Gallagher to double his account and make it 2-1 with a 92nd-minute finish from Palmer’s cutback pass.
Palmer would add his second assist just minutes later, breaking away on the counter-attack before rolling through for Fernandez to coolly beat Henderson.
It is a cruel blow for Hodgson’s side, who are 15th and just five points clear of 18th-placed Everton – Palace’s next opponents on Monday at Goodison Park.
Chelsea sit 10th in the league table before visiting Manchester City on Saturday. Until then, Gallagher will be the toast of the blue side of west London.
