West Brom fullback Allan Nyom insists they can shock Chelsea this weekend.
Tony Pulis' side face a huge task this Sunday if they are to get anything from their trip to Stamford Bridge.
But Nyom told the club's website: "We did very well last weekend against a team who was in a similar position to us in the league table.
"The game showed how hard we have to work week in, week out to get results in the top division.
"I have a lot of respect for Watford, their players and their fans but I was pleased we managed to get the three points.
"Chelsea are on a great run. We know it will be a very tough game.
"But anyone can beat anyone in the Premier League so we'll be going there looking for a positive result."
