Scott Wright admits the Rangers dressing room was "buzzing" after Alfredo Morelos broke his Celtic duck.
The Ibrox star registered a first derby goal in 15 attempts to secure a 1-1 draw for the Premiership champions on Sunday.
Steven Gerrard 's side fell behind to Moi Elyounoussi's header before Morelos turned in at the back post following Leon Balogun's flick-on at a corner.
The Colombian's struggles in front of goal in the fixture have been well-documented and he himself celebrated by letting off smoke bombs in the garden with his wife on Sunday afternoon.
And Wright revealed his team-mates were equally jubilant with their talisman's strike.
He said: "Everybody is buzzing for (Alfredo). He has a great mentality and as a striker, he obviously wants to score goals - we all know that.
"He hadn't scored in an Old Firm, but it is not something he had thought about - he just wanted to play his game and we are delighted for him that he has managed to get his goal today."
Wright's appearance as a second-half sub was his first in the derby following a January move to Rangers from Aberdeen.
And the forward insists he's grateful Gerrard trusted him to make an impact with the match finely poised.
Wright added: "It is great that he has got that faith in me and I think it is something you really work hard for is that trust from the manager.
"All I can do is to keep working hard at the training ground and to work hard in games when I get the minutes and try to repay that trust.
"It is a great game to be involved in, but it is a game we want to come and win and get three points and a clean sheet.
"Something we pride ourselves on is clean sheets - you have seen that through the season but unfortunately we haven't done that today and we are disappointed to come away with a draw."
