Former Chelsea striker Chris Sutton believes West Ham are in "disarray".

The Hammers were beaten by Southampton at home on Sunday.

"It's been quite frankly embarrassing from West Ham," Sutton told BBC Sport. "It's not a crisis, but Slaven Bilic has some major surgery to do."

Sunday's loss followed defeats by West Brom, Watford and Manchester City.

"They had a big chance to put it right but they are in disarray," said Sutton. "Can you blame the fans who left early? They had seen enough.

"It's a massive job for Bilic now. He did enough last season to warrant patience at this stage. But their next three games - Middlesbrough, Crystal Palace and Sunderland - he cannot afford to lose."
