Newcastle United striker Ayoze Perez has been brutally honest in his assessment of the club's squad, telling the BBC that the Magpies do not always work as a team, and has insisted that something has to change quickly at St. James' Park.
The 22-year-old striker accepted that the situation the club finds itself in is a dire one, and suggested that the squad have not shown enough team spirit in recent weeks.
Perez told BBC Newcastle: "In some moments we are not a team, we are not as one. Something has to change.
"It's not enough - we have good quality in the dressing room, but during this season we have not shown it. We need to be a team.
"We have been playing good football at home - winning games. That has been key for us - playing at home. I don't know what happened but we have to change something."
Saturday's 3-1 reverse against the Cherries was so distressing for Newcastle fans because, as alluded to by Perez, the club's home form in recent weeks was its only real saving grace.
The Magpies had lost just two of their last 10 Premier League matches in front of their own fans prior to this weekend, something on which plenty of hope was being rested given the club's seven-match losing streak away from home.
A return to losing ways at St. James' Park has come at a terrible time for McClaren's side, who face a pivotal Tyne-Wear derby against rivals Sunderland in their next home match.
