Four games on Stuart Armstrong is convinced that Celtic have improved out of all recognition from the side that lost 7-0 to Barcelona.
The midfielder was a second half substitute in the Nou Camp as Brendan Rodgers side met the full force of the greatest attacking trio in the game.
MSN- Messi, Suarez and Neymar were on fire as Rodgers side were swallowed up as the clock ticked slowly down to the biggest European defeat in Celtic’s history.
Two weeks later Celtic bounced back to draw 3-3 with Manchester City then recovered from a timid 2-0 home defeat from Borussia Monchengladbach to earn a well deserved 1-1 draw away to the Germans.
Revenge won’t be on the menu on Wednesday night but Armstrong’s professional pride will ensure that Celtic do themselves justice against the Catalan megastars.
“They are one of, if not the, best in the world but in saying that, the way we lost was so disappointing,” the midfielder recalled.
“We’ve improved since then and hopefully we bring that into Wednesday night’s game. It’s the Champions League – all the games are high pressure.
“There’s so much up for grabs on Wednesday night. Of course it’s a big ask but if we want to be in Europe after Christmas then we need to take something from the game.
“Every game in the Champions League is a must win. We don’t want a repeat of that game in Spain.
“It’s Barcelona so they are bound to have a few surprises up their sleeves but we’ll hopefully deal with them as they come.”
Armstrong added: “We can’t forget that game entirely. We don’t want to dwell on it either but it’s important we learn from it and make sure we don’t make the same mistakes again.
“That one game didn’t set a trend for the rest of them. We had good performances against Man City and Monchengladbach.”
Armstrong looks certain to start having made the team for the last five matches including two goals away to Ross County and Kilmarnock.
