The Hammers currently occupy the final spot in the relegation zone with just 14 games remaining and they are in desperate form.
David Moyes has been brought in to try and rectify the current problems at the club but the fact is they have lost seven of their last 11 league games.
And things do not get any easier with fixtures against Manchester City and Liverpool to come, as well as Arsenal, Tottenham, and Wolves.
Jenas reckons other teams are in better form right now and thinks it will be very difficult for the east London side to stay up.
“West Ham are having one. Look at their fixtures. Man City and Liverpool away. Resurgent Southampton, not easy, at home. Arsenal and Spurs away and Wolves at home,” Jenas wrote in his column for the Daily Express .
“They are not getting more than three points until mid-April. It is hard to sit here and say they are going down 100 per cent, but I feel Watford are in better form.
“Norwich are gone. Villa, Bournemouth and Brighton are in their mini-league in terms of never knowing what they’ll deliver. It will probably go down to the last game of the season. Everything you hear about at clubs who get relegated you are hearing about West Ham. It’s the horrible mix they have.
“I read Mark Noble saying they have had crisis meetings. I am worried. Do they care? Have they all got clauses where they get their pay cut 50 per cent if they go down? I’d be surprised.
“Once it turns toxic there, I don’t see many players big enough to handle that scenario from those fans. It’s messy.
“The ability is there. Is the mentality?”
West Ham should have claimed all three points in their last Premier League game at home to Brighton but squandered a a 2-0 and a 3-1 lead to draw 3-3.
There seemed to be a new manager bounce when Moyes came in but the team are now well and truly back to their old tricks and are in real danger of resigning themselves to Championship football once again.
