Bayern Munich, Real Madrid, who the devil are you trying to kid? So the famous terracing chant goes. Well, not quite. Adam Idah subscribes to the theory behind it, though.

The striker is no respecter of names, or reputations. Perhaps that’s why, despite breaking his goal drought with a sensational double at Villa Park on Wednesday night, the big man appeared neither up nor down about his personal achievement amid a collective defeat for Celtic.

So, when it was put to Idah that another intimidating tie awaits his team in tomorrow’s draw, with the format of the new Champions League meaning they can only face either of the afore-mentioned members of European royalty in the play-off stage, he served a pointed reminder about who it is that he and his teammates represent.

Something, he admits, even they may forget from time to time, particularly when facing off against the continent's elite. But something they remembered just as it looked as though they were about to go under during a fraught opening against Aston Villa.

“I think that's probably the biggest learning curve we've got from Dortmund,” Idah said.

“When you play these big teams, you might go in and get a bit timid.

“It's a big team, but so are Celtic. We're one of the biggest clubs in the world and I think people forget that sometimes.

“We've got unbelievable players and I'm sure other teams look at us and think the same thing. We can't be afraid to play these teams.

“I think from that Dortmund game, when we did go down, it was almost that fear of we don't want to play football and I think on Wednesday, it was ‘right, we've had a bad start, but we can get back into it?’ And we did.

“I think at this level, that's where you need to be fully on for 90 minutes and we probably lacked that in the second half a bit, but it's another learning point for us to take the positives from it.

“I think that's what everyone wants to do. It's to play in the Champions League first and then to get the goals, it's an added bonus.

“Wednesday was great for me personally, the result was obviously disappointing, but I think this campaign has been fantastic.

“If you said to us at the start of the season we'd be here, we'd bite your hand off it. I think the boys have been fantastic. It's time for us to push on now.

“We know the level this is. We've got full confidence and belief that we can go and achieve good things.”

All that is not to say that Idah wasn’t pleased with his own contribution against Villa as he bagged his first goals in 15 appearances, but it seems that he was the least concerned of anyone connected with Celtic over his recent barren run.

“To be honest, I think everyone thinks I was frustrated, annoyed and disappointed, but it doesn't really bother me,” he said.

“I'm going to have this probably so many times in my career where I go through a spell where I don't score. I just have to keep working hard, doing my bit for the team.

“In this day and age, as a striker, you're not there just to score goals. You need to do other bits defensively and do bits for the team. That's what I can do when I'm going through that spell.

“It's an added bonus to get the goals and it's a great feeling.

“To be honest, I think people have seen what I can do before. I'm not going to play great every single game. People need to understand that nobody is perfect and so many players have gone through spells that are probably not doing great and not scoring.

“I know I can do it. I've been doing it before. I've played in the Premier League. I know the level.

"It's just about going out and doing it now and that's the thing for me, is to have the confidence to go out and just do what I can do.”

It was certainly a good start for Idah as he looks to stake his claim to become the main striker at the club following the departure of Kyogo Furuhashi.

Though, with manager Brendan Rodgers clearly stating that he wants another forward in the door before the transfer window closes on Monday, and with reports of talks progressing on the possible signing of Brondby striker Mathias Kvistgaarden, he also knows he won’t be able to dine out on his Villa Park showing for long.

“Any striker wants to play all the time,” he said.

“Kyogo's been fantastic. He was a great player, he's a legend at the club.

“It was good, playing with him, watching him, he was an unbelievable player, but now it's up to me.

“I've got big boots to fill, and it's great for me, it's great motivation. I just want to keep the spot now and keep going.

“There's still some young lads in the team that can come here easily and take the spot, so I still need to have that mindset of playing well every week, getting the goals and doing my bit.

“It's a great opportunity for me to go out and try and earn a spot and I'm looking forward to it.”
