Rangers defender Ugo Ehiogu has described his shock after scoring the winning goal on his Old Firm debut.
Ugo Ehiogu said he was shocked to score against Celtic
The former Middlesbrough stopper, 34, beat Celtic keeper Artur Boruc with a 50th minute overhead kick in Sunday's 1-0 derby win at Celtic Park.
"It was incredible. To score in such dramatic fashion to decide my first Old Firm game - I couldn't have written a better script," Ehiogu said.
"It was probably my best goal ever. It was one of those surreal moments."
Ehiogu's goal gave Rangers their first win at Celtic Park in two years, and the defender said he was delighted with the victory.
It wasn't until I heard the roar that I realised that it had crept in
"I thought the keeper had actually saved it because I saw him get a hand to it.
"But it wasn't until I heard the roar that I realised that it had crept in."
Celtic midfielder Aiden McGeady claimed he should have been awarded a penalty when Ehiogu fouled him inside the penalty area in the first half.
But the Gers defender said he did not believe it was a penalty.
"There was a slight tangling of legs," said Ehiogu.
"He certainly didn't have the ball under control and he seemed to run into a group of legs one of which was mine.
"I thought it would have been extremely harsh if it had been given."
Ehiogu said the victory set Rangers up for the second leg of their Uefa Cup tie with Osasuna on Wednesday.
Following the 1-1 draw at Ibrox, Ehiogu believes Rangers can progress in the competition.
"They didn't show us anything to be worried about and if we can perform as well as we can and keep it tight then we have a chance," he said.
