Pat Bonner claimed Kieran Tierney and substitute Tom Rogic were the only Celtic players who delivered the goods in their crushing Scottish Cup defeat to Rangers on Sunday.

Mark Warburton’s side won a pulsating penalty shoot-out in a thrilling semi-final clash at Hampden Park to book a place against Hibernian in the final next month.

Goals from Kenny Miller and Barry McKay had twice give Rangers an advantage but Erik Sviatchenko and Rogic produced equalisers for Ronny Deila’s side.

The Scottish Championship side then kept their nerve in the penalty-shoot out with a 5-4 win that was confirmed when Rogic smashed his spot-kick over the crossbar for Celtic.

Parkhead legend Bonner was unimpressed with the performance from his former team and he does not believe the blame should lay at Deila’s door.

“Young Kieran Tierney was one of the best players but they rest of them didn’t really perform, until Rogic came on,” Bonner told BBC Sportsround, as quoted by the BBC website.

“I thought Ronny Deila did a good job at half-time. He really got them to come out and put Rangers 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 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.

“They still have the league to look forward to but it is going to be a tough four or five days for them.”

Former Celtic manager Neil Lennon went a step further and claimed there has been a shift in the Old Firm rivalry following years of dominance from his former club.

“The better football team came through,” Lennon told Sky Sports 2 after the match. “It pains me to say that. For years, Celtic have had the history of playing good football. It was always a physical battle with Rangers but we always felt were the better football team. On today’s evidence the tide has definitely turned.

“Rangers handled the occasion and the nerves brilliantly. Celtic were disappointing, even though they had good chances to win the game. They didn’t do enough and didn’t have enough spells of pressure.”

The latest Rangers news is that the Light Blues will face Hibernian in the Scottish Cup final on 21 May.
