The FA Cup throws up an unlikely west London derby as European Champions Chelsea travel to League One Brentford on Sunday 27 January.
Rafa Benitez makes the short trip to Griffin Park hoping for a prosaic, predictable win against Uwe Rosler's play-off chasing Brentford. The cup clash will be the first meeting between Brentford and Chelsea for 63 years.
The Chelsea manager wil be desperate not to go out of a second cup in one week, after exiting the Capital One Cup against Swansea City. Chelsea are the current holders of the FA Cup and the competition represents their best remaining chance of silverware this season.
The fourth round clash will be Chelsea's first outing since Eden Hazard sparked a controversy by kicking out at a ball boy at Swansea.
The Belgian playmaker is unavailable as he begins his ban for the incident, with the prospect of a longer spell on the sidelines after the FA launched a probe. David Luiz will miss out with an ankle injury.
Promising midfielder Harry Forrester is expected to start for Brentford, after Rosler rested him for the midweek League One clash against Leyton Orient. Meanwhile, Clayton Donaldson poses a goal threat with four goals in the FA Cup so far this season.
Bees' boss Rosler thinks the Chelsea millionaires may get a shock when the sides line up on Brentford's bumpy pitch.
"I still think their players will underestimate us. It's a human reaction," said Rosler.
"I was as a player the same and I think that is our chance. We have to believe in our chance and we have to go for it," reported the Daily Mail.
"We want to impress. We want people to take notice of Brentford."
Chelsea boss Rafa Benitez identified the pitch at Griffin Park as a potential problem.
"We need to deal with a different team in a different pitch but I cannot explain too much about what we do. It's part of our game plan and how we approach the game in terms of tactics," reported Sky Sports.
"We will use different players but the question is how many of these players can you use to keep the level and have fresh legs. We have an idea."
Brentford v Chelsea, FA Cup fourth round. Kick-off is at 12noon GMT on Sunday 27 January 2013. Live TV coverage starts on ESPN one hour earlier.
