Under-fire Hull boss Phil Brown has admitted his relationship with some players is becoming strained after the heavy defeat to Liverpool.
The 6-1 loss at Anfield piled the pressure on Brown with Hull sitting second from bottom of the table after a poor start to the campaign.
Hull chairman Paul Duffen has jumped to the defence of Brown following calls for his head after two heavy defeats in the last week to Everton and Liverpool.
Brown was left incensed by his side's defending against Liverpool and he admits turning fortunes around is the biggest challenge he has ever faced.
"Certain people in the dressing room are backing away from their responsibility," Brown told The Guardian. "You would have to be a blind man not to see that.
"Look at the teenage lad [Liam Cooper] making his debut. They should have helped him but didn't and he could be scarred for a long time by that.
"The most important relationship in any football club is between the manager and chairman but the relationship between manager and players is important, too.
"It has taken a battering to a certain extent with certain harsh words flying around.
"This is the biggest challenge of my managerial career but I am confident we can confront it head on and win this challenge."
