The Nigerian international striker is gearing up for his first trip to Parkhead in tomorrow’s top of the table clash.
Philippe Clement’s side can close the gap to two points, with two games in hand, over their rivals with a victory.
Dessers is gutted no Rangers fans will be in attendance but hopes to give the watching Gers supporters a reason to be cheerful.
He said: “We are looking forward to the game.
“It would be amazing and a dream to score the winner.
“When you sign here you know the Old Firm and to score in that game is something I dream of.
“I hope tomorrow will be my first goal in an Old Firm game.
“There are no Rangers fans going and it is a pity.
“These are moments you want to share with the fans, but it is what it is.
“As players we can’t change a lot about it, that is for someone else to worry about, but we have to focus on what we have to do.
“I expect it to be an intense afternoon, but I like that.
“We played Betis a few weeks ago and I like these games when everyone is against you and I think the team like it too.
“I am looking forward to it.”
Dessers has hit four goals in his last seven appearances and his become a vital focal point for gaffer Clement following injuries to Danilo and Kemar Roofe.
The hitman reckons he is finally showing the fans why he was brought to Ibrox but believes there is more to come from him.
He added: “The start was pretty rocky for me, and for the team, but you can see the results the last few months the team and myself are improving and we are in a good place.
“The gaffer brought clarity for everyone, he has a style of play that suits me very well and the other players.
“He brings a good structure and I like that as a player, we know what to do, we can go on the pitch, we can switch to auto-pilot and do our job.
“We are playing more fluidly, we have more chances and I think for me, I have got a bit more confidence.
“I am in better form but there is more to come. As a striker when the goals start, then they keep coming.
“At Rangers there will always be other strikers with quality.
“I am just trying to provide for the team whenever they need me.
“I try to stay positive and do my job.”
Dessers was gutted to see Wednesday’s Premiership clash with Ross County postponed after the weather meant the Staggies couldn’t reach Glasgow.
But he hopes the unscheduled break could work to Gers’ advantage.
He said: “I wanted the Ross County game to go ahead.
“I had family over and they wanted to see the game. When you are in the winning mood you want to play all the time.
“I was disappointed, but it is OK. We had a bit of rest and hopefully we can show that freshness against Celtic.”
