West Ham defender Vladimir Coufal has urged calm after defeat to Chelsea.
Coufal insists they can bounce back.
“It is very difficult to describe the feelings [in the dressing room] right now," Coufal said. “We feel we could have taken some points from Stamford Bridge - and that we had enough power to get them.
“I am disappointed because we could kill the game maybe, but we conceded a goal instead. I don't think [we switched off]. There was a misunderstanding maybe for the first goal and the second goal there was a cross and we did not cover the player. It is difficult."
Coufal is confident West Ham can bounce back immediately.
“Unfortunately, we dropped too deep in some situations, but we have to keep our heads up and keep going," he said.
“We can take many positives from this game. We are building something new; we are trying to play a different way than how we played in the last two seasons."
