David Moyes has told his West Ham players that they must improve their performances if they want to keep climbing the league table.
The Hammers take on Wolves on Sunday in a huge game in the top four race.
The Molineux side are just two points behind the Irons and have a game in hand on the Irons, who have only won one of their last five Premier League games.
Wolves’ ambitions of a top-four finish were dented in midweek, as they lost 2-1 to Arsenal, while the Hammers drew 1-1 with Newcastle last weekend.
And Moyes has now told his players that they simply have to get better if they are to keep the pressure on the top four, starting with Sunday’s game against Bruno Lage’s side.
Speaking to the club’s official website, he said: “I think what gives us a great chance [in this race] is our team spirit, our energy, the attitude of our players.
“We have a brilliant group of players. We are resilient and in a period where we have probably not played at our most fluent best or played as well as we think we can but we are still digging out results.
“I want us to play better. I want the performances to be better. Small things to be better. I think our goalscoring this season has been very good but we have a couple of players that we would like to find goalscoring form especially with European football, FA Cup games coming up. You need everybody to be firing and playing well.
“Defensively we need to tighten up and not give goals away too. Make it much harder for the opposition to get some goals.”
The Irons face a busy week of action and will play Southampton in the FA Cup on Wednesday before playing Liverpool in the league next weekend.
