Goalless Palace may finally find the net
Kick-off 3pm Saturday
Palace have been short of attacking quality and the availability of Zaha, who destroyed Chelsea at Stamford Bridge last season, is a massive boost.
Chelsea, without N'Golo Kante screening the defence, could be more vulnerable than usual but they can make their presence felt at the other end against opponents who are desperately lacking confidence.
Chelsea win and both teams to score
1pt 12-5 general
Wilfried Zaha and James Tomkins are in full training and ready to return but Ruben Loftus-Cheek cannot face his parent club and Christian Benteke and Connor Wickham are sidelined. Scott Dann and Pape Souare face late fitness tests.
David Luiz is available after suspension but N'Golo Kante (thigh) is out and Alvaro Morata (hamstring) and Danny Drinkwater (calf) are doubts.
Crystal Palace have scored in six of their last nine matches against Chelsea.
