Watford defender Christian Kabasele says they need to ease the pressure on Ben Foster.
The goalkeeper made several important stops and almost scored in defeat against Chelsea.
"Without the save of Kepa we would have one point," said the Belgian defender.
"But we can't rely on our goalkeeper to save the team every week, so we will work and see what's happening.
"We lost the game so it's difficult to say we played better. I think the last 20 minutes of the first half was okay, but the main part of the game we didn't do our job."
