Under-fire manager Eddie Howe has criticised Steve Cook for going public about Bournemouth's issues and says the comments are unhealthy in the Cherries' fight against relegation.
Stand-in captain Cook said Bournemouth 'played like kids' following their heavy 4-1 home defeat to Newcastle which put them in serious danger of the drop from the Premier League.
The South-coast side are on a torrid run of just two wins since December and Wednesday's humiliating defeat at the Vitality Stadium left them 19th with six games to play.
Pressure has started to mount on Howe following their disappointing season, but the long-serving manager felt his defender's comments were a hindrance in their fight to stay in the division.
'Listen, I don't think they are helpful for us,' the Bournemouth manager said of Cook's comments, 'When you don't perform well, I think everything needs to be internal - that's always been how I've worked, we keep things in-house, and our opinions of ourselves stay that way.
'I have a duty when I come to the media to tell the truth in respect of what I think of our performances and I don't think it's healthy to view ourselves or read ourselves in that way.
