PAT BONNER claimed Kieran Tierney and substitute Tom Rogic were the only Celtic players who performed at Hampden.
After 2-2 following extra-time, Callum McGregor, Scott Brown and the Aussie squandered penalty-kicks and blew the chance of a Scottish Cup Final meeting with Hibs next month.
The Hoops’ legendary goalkeeper said: “Young Kieran Tierney was one of the best players, but the rest of them didn’t really perform, until Rogic came on.
“I thought Ronny Deila did a good job at half-time. He really got them to come out and put Rangers (sic) to the sword early in the second-half, and again he got them going in extra-time. So, he deserves a bit of credit.
“It is going to be tough for him because the media will apply a lot of pressure on him.
“It is hugely disappointing for Celtic. They should have enough in that team to go and perform better than that in the first-half and take the game to Rangers (sic).
“They still have the league to look forward to, but it is going to be a tough four or five days for them.”
