Crystal Palace boss Pierre Sage has been speaking to the media before Friday's Premier League game against Manchester City at Selhurst Park (kick-off 20:00 BST). Ismaila Sarr has a groin injury and will miss the match. Chadi Riad, who was substituted off injured in the 2-0 loss to Everton, is seeking "specialist" advice - the French boss did not confirm a return date.
