CELTIC striker Moussa Dembele insists that he hasn't dwelled on his penalty miss against Barcelona in September and is confident the Hoops can pull off an upset in tonight's return fixture.

The French striker had the opportunity to equalise at the Nou Camp in the opening round of the group stage, but saw his spot-kick saved by Barca goalkeeper Marc-Andre Ter Stegen.

Dembele assured that the miss hasn't stayed with him, using his opposite number for tonight's clash, Lionel Messi, as an example that even the world's finest can occassionally slip up from 12 yards.

“I didn’t have any pain missing against Barcelona,” he said to the Celtic View.

“As I’ve said before, a penalty is a lottery. Sometimes you miss, sometimes you score. Even Lionel Messi and Cristiano Ronaldo do it. Ronaldinho did it too so it’ll happen to me for sure

“I’ll try to not do it again but it’s probably not the last one. Even the best miss and I’m not the best yet."

Despite the 7-0 deficit that separated the two sides two months ago, Dembele believes his side are capable of producing a much-improved performance this time round. 

“I’m feeling good, even if last time didn’t go well for us, I still feel confident that we can get a result at home against what I would say is the best team in the world," said the 20-year-old.

"We have nothing to lose so we have to go and be proud of ourselves and give everything."
