He says it was the one game he would have loved to play in during his four years at Swansea but never got the chance so he has to settle for second best and watch it from the Liberty stands.
He admits that he will be backing the Swans to win the game and is looking forward to a rare chance to watch his former team mates in action.
There have been rumours of a possible Trundle return as a player since he fell a little out of favour at Ashton Gate but that is not something that either side have said is a possibility.
Speaking to the Evening Post ahead of tonight’s game, Trundle said “I haven’t been able to watch Swansea as yet this season because our fixtures tend to clash now that we’re in the same division,” says Trundle, who left for Bristol City 14 months ago.
“I will be wearing my black and white scarf and supporting the Swansea lads.
“It’s a massive game, and I’ll be itching up in the stands because it’s one of the fixtures I really wanted to play in during my career.
“I’m gutted that I won’t be playing
“I have spoken to a few of the lads at Swansea and I know they’ve been really looking forward to the game.
“They can’t wait, especially the British boys who know it’s one of the biggest rivalries around.
“I’ve got to admit I’ll be feeling pretty jealous when they come out on to the pitch, but it will be nice just being there and seeing what it’s like.
“I’ve heard so much about the games in the past that I want to experience it.
“Playing in the game would have been unbelievable, but I’m looking forward to being at the Liberty and sampling the atmosphere, because it should be fantastic.
“Obviously I’m a bit down because I’m not in the side at the moment,” he says.
“I enjoy playing football and I love matchdays. That’s when I’m at my happiest and it is a bit hard at the moment.
“It was nice to get a goal last week and give myself a bit of confidence, but I don’t know whether I’m going to be in the first team any time soon.
“That’s out of my hands. All I can do is keep training hard and playing in the reserves and hope I get a chance.
“I think Roberto will play his first team because he knows all about the rivalry and he knows the fans will demand it. It will be a tight game, but I think Swansea will win 2-1.”
Trundle will also have the chance to face his former team mates in December when they travel to Ashton Gate although there is no guarantee that the former Swansea man will be involved
“I hope I’ll be involved then because, as I’ve said before, I never got the chance to say a proper goodbye and it would be nice to see the Swans fans in a first-team game again,” he says.
For now Trundle is left watching on from afar — tonight aside, of course — and has been impressed with Swansea’s start to life in the second tier.
“I knew they would do well. People have asked me if I think Swansea will go down and I’ve told them there’s no chance,” he goes on.
“They are a good footballing side with a lot of players who should have been playing Championship football a long time ago.
“They have a good management team, too, and I can see them doing well throughout the season.
