Bournemouth manager Eddie Howe fears his team is losing their playing style.
Their present run of only one victory from nine means they have slid to 13th and remain at risk of finishing even lower.
He said: "You are looking week in, week out to see a clear identity, a clear way of playing, knowing you are improving every game.
"But in recent weeks we haven't seen the clear philosophy we want, and that hurts me more than anything. So we will have to go away and figure out why we are not seeing that and work towards definitely delivering a better product.
"We are going to have to review everything we do.
"Very few times have I felt like this during my management career when I've looked at a team and not been able to see what we've worked on."
