David Weir admitted Rangers need to learn a number of lessons fast after a humbling 4-1 home loss to Sevilla in the Champions League tonight.
Rangers were outclassed by the Spaniards, who scored four times in the space of 25 second-half minutes.
"I don't think (the score reflected the game), but at the end of the day it's a big defeat for us, so obviously we're not happy with it," Weir told Sky Sports.
A pair of big refereeing decisions went against Rangers with Steven Naismith appearing to be felled inside the area by Abdoulay Konko, while Sevilla's opening goal came from a questionable free-kick awarded against Weir.
However, the captain does not see any value in criticising the referee.
"I don't think it was a free-kick, but regardless the referee gave a free-kick and we've got to do better than that. Decisions go against you but I was disappointed with all the goals, they were soft.
"I also thought it was a penalty, but we have to look at ourselves before we look at the referee. The goals are too soft, so we need to look at that.
"There are things we need to eradicate."
Naismith insisted it was a "stonewall" penalty.
"I don't understand why I'd go down when I'm through on goal," the striker said.
"He's caught my foot as I went to strike it, but he's not given it. In my eyes it was a stonewall penalty.
"(The referee) said afterwards he thought I was already on the way down before there was any contact, but I'm not worried what he thinks, I know it was a penalty.
"If it was a dive I should have been booked."
One positive for Rangers is that Romanian champions Unirea Urziceni held Stuttgart to a draw, leaving the door open in Group G.
But they must now pick themselves up quickly with the Old Firm clash with Celtic looming at the weekend.
"One result is not going to make or break your Champions League campaign at this stage," Naismith added.
"There are some harsh lessons here, we need to look at our mistakes, look at the positive notes and go on from there."
