Rangers boss Philippe Clement was pleased his players felt frustrated with their performance against Aris Limassol and challenged them to be at their best against St Mirren on Sunday.
The Ibrox side drew 1-1 at home with Aris on Thursday, leaving their hopes of Europa League progress in the balance.
Clement revealed the discontent among the team about how they had played but told them they had to turn things around quickly for the visit of St Mirren in another crucial Premiership game this weekend.
“It was the first time that I felt real disappointment in the dressing room,” the manager said. “They were not happy with their performance.
“That is a good thing that they were not happy with their performance, but now we need to stand up on Sunday and show our best level, with what we are going to need to win that game.”
Clement has said that he will rotate his squad through a busy spell that sees Rangers play nine times in the next 30 days but said that part of adjusting to the quick-turnaround was mental more than physical.
He said: “It is about making the mind-switch really fast every time and not to lose confidence for whatever reason, and go full out and get the three points from the first second the game starts.
“St Mirren will make a wall and make transitions and set-pieces like we have a lot of games in the Scottish league. So there will not be a big difference in that way and they are going to fight.
“For them, games against Rangers are maybe the biggest game of the season, so we know that.”
