The former Nottingham Forest defender has been one of Celtic’s most consistent performers this season and has looked at home in the Champions League.
Beating Barcelona will remain a career highlight for all of the Celtic players but it’ll be a bittersweet moment if the clubs’ interest in the Champions League ends on Wednesday night.
“Obviously you don’t want to win a game like that and drop out,” Wilson said. “It would be pretty pointless.
“Getting that win put us in a position to qualify so we want to see it through. I just know it was a very special night for us all.
“Everything about it was incredible. Everything seemed to come together for the 125th anniversary and even the Barca players seemed to find it all a bit unreal. It was a great night.
“Two of my best mates came to that game, one an Arsenal season-ticket holder and one a Man United fan. They said they’d never seen anything like it.”
Looking to Wednesday Wilson added: “We’ve got a massive game against Spartak now and it’s going to be a great atmosphere. We’ll go into it with confidence.
“I’ve enjoyed the Champions League. It’s been a bit overwhelming but like the rest of the lads I’ve just got on with it.
“Spartak are in a bit of a crisis but we won’t take the game lightly, they have some top players.”
