West Ham beat Chelsea 2-1 in the League Cup quarterfinals to send the Blues crashing out of the tournament.
West Ham Slaven Bilic believes his team can perform that task again as they host Chelsea on March 6 in the Premier League.
He said: “That was a really great game, we played really good.
“They didn’t start with their best team, let’s say, but in the second half they put everybody in and we deserved it.
“Hopefully we are going to do the same. They are doing fantastic, they are winning and they are everything.
“They are solid and up front they have that unbelievable pace, strength and quality that is hard to stop.
“But we are a good team now, and we have been really good for a period of seven or eight games.
“We are good physically, we are good mentally, we are good on the ball, we are good in transition, and that is why there is always belief.”
West Ham played a 1-1 draw with Watford at the weekend and are currently ninth on the table.
