PEDRO CAIXINHA admits Rangers do not deserve to be best of the rest if they fail to beat Aberdeen on Sunday.
The Ibrox boss watched his new team slip 12 points behind the Dons after a goalless draw against Kilmarnock at Rugby Park last night.
With just seven games remaining, time is running out for Gers who have still to play Derek McInnes’ men twice in the run-in.
The Portuguese coach said: “It’s getting difficult. We know we need to play twice against Aberdeen and that they have to play against all of the top six again.
“The maths says it can still be done, but the next game will be crucial to understand if you are able or not.
“If you don’t win Sunday against Aberdeen, you don’t deserve to be in second position. But that is my challenge. It is something we need to prove to ourselves.
“We are Rangers. We want to fight. At this moment, this is the challenge.
“We are Rangers, we have a culture of winning and getting the three points all the time. So, we cannot be happy drawing the game.
“We need to be reinforcing the players the demands of playing at such a massive club who needs to win all the time.
“We need to be angry when we don’t do it.”
