Crystal Palace boss Sam Allardyce has been left frustrated as his players "have not grasped'' his approach as his attempt to guide the Eagles to safety this season continues to stutter.
Allardyce has overseen just one Premier League victory since replacing Alan Pardew at the Selhurst Park helm on Dec. 23.
A 1-0 defeat at Stoke in their last outing has left Palace 19th in the table and two points from safety, although they can move level on points with 16th-placed Middlesbrough if they beat Aitor Karanka's side in south London on Saturday.
Former England boss Allardyce, 62, has never been relegated from the top flight and kept Sunderland in the division against all odds last season having been appointed in the middle of the campaign.
