Regular starter Adrian is set to miss the final three games of West Ham's season.
A win would also see West Ham keep up pressure on the top four as they look to force their way into the Champions League places at the expense of Manchester City and Manchester United.
Unfortunately, they will have to do so without Adrian. The Spanish keeper injured his calf against West Brom at the weekend and will therefore miss the final three games of the season.
West Ham boss Slaven Bilic has already confirmed that Republic of Ireland goalkeeper Darren Randolph will step in to replace him for a rare Premier League appearance.
Randolph has been a regular in the cups for the Hammers but not the Premier League – featuring just three times in the league this season.
With that in mind he was working hard in training this week to ensure he was at peak condition for three potentially massive Premier League fixtures.
As for the back-up? It seems Raphael Spiegel will be on the bench. The giant Swiss has been impressing in training and for the under-21s recently and will be ready should Randolph find himself sidelined.
