Patrick Vieira says Crystal Palace have to realise the "different level" of teams they have faced recently after picking up two points from their last three games.
Palace earned a second point in four days as they drew 0-0 with Newcastle United at Selhurst Park on Saturday, having scored late on to draw 1-1 with Manchester United on Wednesday night.
Those two results followed a 1-0 defeat against Chelsea at Stamford Bridge last weekend, with the Eagles currently in 12th place in the Premier League at the halfway stage of the campaign, with 24 points.
