The Magpies surrended a two-goal lead to champions Chelsea at St James' Park on Saturday.
Newcastle goalkeeper Tim Krul has called for his teammates to be more vocal as they continue their quest for a first league win.
“I think the coaches said the words which needed to be spoken (after the Sheffield Wednesday loss),” said Krul, in quotes published by the Chronicle.
“We need more people speaking (in the dressing room) - unfortunately that’s not the style of some of the players but it needs to happen.
“We need to take more responsibility and we did that today (against Chelsea).”
The Dutchman failed to prevent the Magpies’ two-goal lead from slipping against Chelsea on Saturday and should have done better with Willian’s in-swinging free-kick.
Despite the end to the game, Steve McClaren will take confidence from his side’s performance - in the first-half especially - after what has been a dismal start to his tenure.
The return of Mitrovic seemed to spark Newcastle into life and a first win shouldn’t be too far away if the level of performance shown against Chelsea is maintained against lesser opposition.
Krul’s words regarding the lack of a vocal presence in the dressing room will be a concern however, and with the lack of Premier League experience in the Magpies’ squad, it’s not a surprise.
Large sums were spent this summer but none of the new recruits have experience in England, while the likes of Siem de Jong, Kevin Mbabu and Rolando Aarons have also seen limited game time in the top flight.
