Callum Wilson says Newcastle lost ground at the start of the season because they were not fit enough for the pace of the Premier League.
The striker is the latest player to suggest the squad was not in peak condition under former boss Steve Bruce and that fitness has only improved for the arrival of Eddie Howe.
Sportsmail has reported previously how there was concern among players over training and preparation, with excessive days off a particular point of ire.
Newcastle are without a win in 14 matches this season and did not look as fit as the opposition during the opening weeks, a suspicion confirmed by Wilson.
