Ruben Amorim has admitted Manchester United's poor form has left his players "afraid on the pitch" ahead of their daunting trip to Liverpool on Sunday.
United have lost their last four games -- including three Premier League defeats in a row -- without scoring a goal.
And as Amorim prepares to take his team to league leaders Liverpool, he said the miserable run is causing "anxiety" within his squad.
"They [the players] are anxious, and sometimes afraid on the pitch," Amorim said.
"We have to cope with that. We need the leaders to step up to help the other guys and I'm the most responsible person here to improve the performances.
