Chopra reckons there is very little work being done on shape and tactics compared to previous boss Rafa Benitez.
Speaking to talkSPORT, Chopra revealed: "I've spoken to some senior players at the club – I won't mention their names – and under Benitez everything was drilled into them on the training pitch: the team shape, how they were going to play – every day.
"Bruce has come in, and some of the players don't know their jobs – they are not really working on their shape.
"At Newcastle for two or three years those players have overachieved under Benitez.
"But I don't think some of the players are good enough for the Premier League. They need coaching – they are not good enough."
