Ex-Celtic striker Andy Walker has told Sky Sports that some of the Rangers squad have 'let the supporters down' this season.
Rangers are pushing for promotion back to the Scottish Premiership, but are now looking at third place in the Championship after a 2-2 draw with Falkirk on Saturday.
That result means that Rangers now lie one point behind Hibernian, and would leave them in third place - and a more difficult run through the play-offs, given that they would have to play two more games than the second placed team.
New manager Stuart McCall has impressed so far since replacing Kenny McDowall in March, but Saturday's draw against Falkirk has put a real dampener on Rangers' promotion hopes.
They now face a final day trip to Tynecastle to take on already-crowned champions Hearts, in a game which will see them lift the title in front of their home fans.
With a win needed against Hearts and a favour from Falkirk, who face Hibernian, Rangers' hopes of clinching second place look bleak.
Now, former Celtic striker Walker has told Sky Sports that Rangers' big players have let the supporters down time and time again this term, and must now prove their worth as Rangers enter a crucial stage of the campaign.
"Rangers really have to rely on some big performances from the allegedly big players, because they have let the supporters down so much this season. They really need to raise their game for what is an enormous part of the season," said Walker.
The likes of Lee McCulloch and Kris Boyd have come in for criticism this season, and McCall will need his experienced pro's to contribute if Rangers are to return to the top flight this season.
