The Magpies need a quick turnaround of fortune if they are to avoid sliding further into trouble.
The Magpies stormed into the lead against Chelsea at St James Park on September 26th, via a well-taken Ayoze Perez goal, and could have added to their tally.
Chelsea came back into it after Georginio Wijnaldum made it 2-0 in the second half however, and eventually snatched a draw in the closing stages of the game.
McClaren’s men started similarly well against Manchester City at the Etihad two weeks ago and took the lead through an Aleksandar Mitrovic header.
Sergio Aguero levelled things just before half-time and the second half brought about a complete collapse, with a 6-1 scoreline heaping more misery on the struggling Magpies.
Newcastle now face a run of winnable games and McClaren has made it clear to his players that they must replicate the first 45 minutes of those two games if they are to pull themselves out of their slump.
“We need the kind of response from the players and the crowd as if we are playing Chelsea. What we have done in the last two games is play well, really well for 45 minutes,” said McClaren, in quotes published by the Chronicle.
“We showed the players the 45 minutes and said: ‘All you have to do is produce that for 90 minutes’. If they do that they will get results.”
