Former Chelsea striker Chris Sutton has branded Simone Zaza "pathetic" for West Ham.
Sutton was speaking with BBC Sport after the Hammers' defeat at home to Southampton.
"When players like Manuel Lanzini and Dimitri Payet, who were great last season, perform like that they are in trouble," Sutton said.
"Zaza? He was pathetic. They need to snap out of it and quickly. The big problem is they are disjointed and concede goals.
"The players have a responsibility to provide the energy, passion and drive to get this crowd up. There might be teething problems with the stadium but the team on the pitch are not helping.
"We can make excuses about off-the-pitch stuff but the players have a responsibility to do better."
