The Hammers boss has come under criticism this season given the club’s current placing at the bottom of the, and Cottee believes the former Portsmouth manager needs to show some leadership in order to improve the team’s current form.
"A lot of it comes back to the manager. He’s got to inspire them," Cottee told talkSPORT.
"I know they’re multi-millionaires and they get too much money, but they do respond to the management and I wonder what on earth is going on at the club. There doesn’t seem to be any leadership.
"Grant wasn’t my choice and I didn’t want him to get the job. But now he’s got it they need to support him and try to get through this difficult period.
"But I watch him interviewed and see him on the side of the pitch and I just don’t get it. I fear for them.
"The players are screaming out saying they need help and I’m not sure they’re getting it. Everyone connected with the club is so down about things and there's almost a feeling of accepting that we’re going to get relegated."
The former striker also insisted that the Israeli manager wasn’t the only individual at fault, and the players need to take a brunt of the criticism.
"It’s no good just blaming the manager. The players are the ones on the pitch and they’ve got to take responsibility," he added.
"Someone’s got to inspire them. We’ve got Scott Parker, and he’s unbelievable, but we need 11 of them."
The Hammers are set to meet Arsenal this weekend, who are on a four-game winning streak that has included a 3-0 victory over Manchester City at Eastlands, and Cottee is worried his former club could be on the wrong end of a thrashing.
"I fear for them [West Ham], I really do. If Arsenal get an early goal it could be any score," Cottee continued.
"And I’ll tell you what; they’ve got to be men when they go to the Emirates.
"If they just roll over and get beat 8-0 they won’t look forward to the next game at Upton Park, that’s for sure."
