Newcastle United are second-bottom of the Premier League after an already-dismal season hit a new low.
Crystal Palace dished out some capital punishment to Steve McClaren's inept side this afternoon.
Alan Pardew's team ran out 5-1 winners at Selhurst Park – and it could have been worse.
And the result saw Sunderland – who beat Stoke City at the Stadium of Light – and Bournemouth climb above Newcastle in the table.
Head coach Steve McClaren had talked of a "feisty" reaction on the training field to last weekend's 3-0 home defeat to Leicester City on the eve of the match.
But his team were anything but feisty at Selhurst Park, where Newcastle were backed by 2,800 fans.
And United's inability to defend was particularly worrying.
Fit-again Jack Colback returned to the starting XI in place of the injured Cheick Tiote.
And McClaren also recalled Papiss Cisse to his starting XI – Aleksandar Mitrovic dropped to the bench – and the striker put Newcastle ahead with an 10th-minute header from a Daryl Janmaat cross.
However, United's performance quickly unravelled, and their lead lasted just four minutes.
James McArthur levelled with a defected shot, and Palace took advantage of some hesitant defending to take the lead, with Yannick Bolasie scoring the first of his two goals in the 17th minute.
Wilfried Zaha was the beneficiary of more sloppiness at the back before the break.
The winger's angled finish from a Connor Wickham cross made it 3-1.
McClaren switched to a three-man defence at the break – Jamaal Lascelles replaced Ayoze Perez – but things got worse two minutes into the second half.
Damien Delaney headed a free-kick towards Bolasie, and he beat his marker to the ball.
Palace went on to dominate the rest of the game, and McArthur added a fifth in injury time.
McClaren – whose side are two points adrift of safety – must now someone get a reaction from his lifeless players ahead of the home game against Liverpool on November 6.
