West Ham boss Slaven Bilic is demanding passion from his players for their EFL Cup clash with Chelsea.
Bilic wants his players pumped up as they attempt to knock out the Blues and reach the quarter-finals.
"I don't want them to be calm, no, no," he said. "I want them to be focused and up for it, but at the same time not to do anything stupid.
"Before these games you don't need a special motivation, as it is Chelsea. You can calm them a little bit down, but you want them to be in a state that they can't wait for the game to start."
