The Blues will drop to third place if Manchester City earn a result against Everton on Saturday evening, but with Liverpool not playing until Monday, Jose Mourinho's team will move to the top of the standings if they win at Stamford Bridge.
Norwich arrive in West London on the back of five successive defeats, and failure to secure a result at Chelsea will leave the club on the brink of relegation to the Championship.
Norwich City: WLLLLL
Possible starting lineups
Chelsea: Schwarzer; Ivanovic, Azpilicueta, Cahill, Terry; Matic, Lampard, Schurrle, Willian, Salah; Eto'o
Norwich City: Ruddy; Whittaker, Olsson, Martin, Turner; Johnson, Snodgrass, Fer, Howson, Redmond; Hooper
