Most recently, West Ham won away to Wolverhampton Wanderers on Monday night, as a very impressive first half helped the Hammers seal three very big points.
Leander Dendoncker got one back for Wolves just before halftime to give a bit of hope for the hosts.
In the 68th minute, Fabio Silva brought the ball down brilliantly and finished off the move to give West Ham flashbacks to their 3-3 draw with Arsenal. However, the Hammers won 3-2 to move into fourth.
On the other hand, Leicester lost to Manchester City in their most recent game at the King Power Stadium.
In the second half, Benjamin Mendy opened the scoring with a smart finish past Kasper Schmeichel.
To secure the win, Gabriel Jesus and Raheem Sterling linked up to pass the ball into the back of the net.
Declan Rice will be missed again through a knee injury, and is expected back in May.
Coming off in the 30th minute against Wolves, Michail Antonio is also a doubt with a hamstring injury.
The Foxes will be without James Justin and Harvey Barnes who are sidelined for a lengthy time with a ACL injury and a knee injury, respectively.
Cengiz Under and Wes Morgan are also doubts.
Caglar Soyuncu is out as the player has COVID-19.
West Ham United: Fabianski; Coufal, Diop, Dawson, Cresswell, Masuaku; Soucek, Noble; Bowen, Lingard, Benrahma.

Ones to watch
West Ham United - Jesse Lingard
The midfielder is one of the most inform players at the moment, in the Premier League, following his explosive start to life at West Ham. The attacking midfielder is at the centre of the Hammers' attack, driving West Ham forward superbly.
The 28-year old was brilliant in all of his games so far for the East London side, being the standout player on the pitch. Settling in very quickly, Lingard has six goals and four assists in eight games, pushing the Hammers towards the UEFA Champions League places.
Leicester City - Jamie Vardy
Despite not scoring since the second week of February, Vardy will look to add at least one more tally to his record, as he faces West Ham. The striker has scored three times before against Sunday's opponents.
His dynamic runs alongside his quick flowing football can make it difficult for any team to defend against.
