West Ham defender Winston Reid believes they face a huge game against Chelsea on Wednesday.

The Hammers host their London rivals in the EFL Cup fourth-round and have already lost to the Blues once this season.

Chelsea snatched a 2-1 victory at Stamford Bridge on the opening day of the Premier League, with Diego Costa scoring a late winner in the 89th minute.

West Ham strongly believe that the Spaniard should have been given a red card after a high challenge on goalkeeper Adrian, when Costa was chasing down a back pass.

Slaven Bilic’s side have endured a difficult start to the campaign but have won their last two matches 1-0, with centre-back Reid scoring the winning goal against Sunderland on Saturday.

West Ham have already been knocked out of the Europa League this season and Reid has recognised the significance of a cup run.

“It is a massive game for us,” Reid said, as quoted by the Evening Standard. “We needed the boost of a win over Sunderland and now we can go into the game really looking forward to it.

“We conceded a goal at their place late in the Premier League game, so it would be nice to get some revenge. A cup run would be good. It was a disappointment for us to go out of the Europa League so early.”

West Ham were eliminated in European qualifiers by Romanian side Astra Giurgiu and their form has dipped since the move to the London Stadium.

Bilic’s side earned a seventh-placed finish in the Premier League last season and were expected to challenge for European places once again.

The return of key players such as Dimitri Payet and Manuel Lanzini through injury has seen them climb up to 15th in the league table, with the club unbeaten in their last three games.

The Hammers will hope to continue the good form and inflict some revenge against Chelsea in the cup.
