Mark Warburton has questioned the decision to relay the Hampden Park pitch just a week before Rangers' Scottish Cup semi-final clash with Celtic.
The Rangers manager saw his side claim the Petrofac Training Cup with a comfortable 4-0 victory over League One Peterhead on Sunday on the problematic national stadium surface.
Warburton and Peterhead manager Jim McInally were unimpressed with the standard of the pitch, with McInally even dubbing it "dangerous" after four of his players were left hobbling with injuries.
Hampden Park Ltd, who operate the venue, have confirmed they will put down new turf in time for Gers' clash with Old Firm rivals Celtic on Sunday and Saturday's last-four meeting between Dundee United and Hibernian.
It comes just five weeks after the pitch was last re-laid - the fifth patch-up job in seven years - after Hampden's pitch suppliers admitted the grass had failed to bed in properly.
But Warburton is not convinced the plan will work and reckons Hampden bosses are paying the price for not following the likes of Murrayfield and their costly hybrid surface.
He said: "The pitch was difficult. It was hard to play on. I know a lot of work is going on but you've got to question how a new pitch can bed down in such a short time.
"My concern is if we have any adverse weather on the Thursday and Friday then have Hibs and Dundee United playing on it on Saturday before we play Celtic on Sunday. I'm not sure how you bed in a new pitch in three days' time.
"I understand there's problems and you have to find a solution as swiftly as possible. But it is surprising.
"How much does it cost to relay the pitch? With the amount of times it is being done, should you not go for the more expensive option in the beginning which proved to be the cheaper option in the long run?"
McInally said he was disappointed his team failed to ask more questions of Gers and gave an equally scathing assessment of the pitch.
"The ground is so hard, there is a skim on top of it," he explained. "Three of our players picked up groin injuries. Ryan Strachan has not missed a game all season but had to come off with a calf strain.
"It's better for it to be relaid than to try and play on that if you are trying to play two semi-finals next week.
"It is in really, really poor condition. It is solid. If you soak it, then it becomes a bit dangerous. I don't think it could be any worse, no matter what they do to it, but I'm no grass expert."
