Crystal Palace manager Patrick Vieira has admitted this weekend's match against Leeds United will be "challenging" as Jesse Marsch's side prepares to travel to Selhurst Park.
The Whites have had a good start to the season as they sit in 12th but are winless over their last four matches - their last win coming back in mid-August in the form of a 3-0 win over Chelsea.
The Eagles, on the other hand, sit just above the relegation zone having only won one match all season - a 3-1 win over Aston Villa.
