Brendan Rodgers has called on UEFA to sanction clubs who break the financial fair play rules, while maintaining that the gulf between Celtic and other clubs is different from the chasm between the Hoops and the elite European level sides.

Celtic’s team that were beaten by Paris-Saint Germain this week cost £23m to assemble, while the French team’s tally came to something in the region of £500m.

PSG tried to get around the financial fair play regulations by taking 18-year-old Kylian Mbappe on an obligated loan deal – they will pay £133m for the striker next summer – and Rodgers believes that the governing body need to stick to their guns if there are regulations in place.

“Time will tell what FIFA do,” said the Celtic manager. “The starting point is having a sanction in place that clubs abide by. You see the clear gap.

“Don’t get me wrong, I can’t complain, because you never know, you might be in that position one day.

“Football is very much financial in every aspect. The money we get from Champions League is massive, but it’s nothing compared to some of these clubs.”

There is an argument that Celtic’s experience in the Champions League is akin to what other domestic clubs go through coming up against the Parkhead side, but the sheer magnitude of individual players is what Rodgers believes is the main difference.

Quality such as Neymar - who cost PSG £198m - and Mbappe are at elite level, something that Rodgers doesn't think is the same as the difference between Celtic and the rest in Scotland.

“It’s totally different," said the Celtic manager. "With all due respect, when you are working with that level of player, you see the difference.

“I understand the relative comparisons that get made.

“But it’s totally different because of that level of player and belief."

Despite that, Rodgers has insisted that although the bar appears to be rising all the time that Celtic will always want to be in there competing.

" It makes it more difficult for clubs like us from countries like ourselves," he said.

“It’s now in place to get even more from the big spending leagues, while teams like us have an extra game to even get there.

“It’s already well under way. It’s difficult, but we need to meet the challenge.

“It’s where we want to be, for many reasons. You want it at the highest level you can, but it’s only going to increase the difficulty as the years go on, because money talks.

“That’s what the people with the money want to see, it’s the brand.

“Listen, it’s where it’s going. The teams in pots one and two are so far ahead financially and they will look to have all the big teams in there after Christmas."

And the Celtic manager is confident that the Parkhead club can push for European football after this year's festivities.

“The objective is to qualify for Europe (beyond Christmas)," heh said. "Take away the top two then these are the games that will really be deciding factors.

“Even then, in comparison to us again, they have a different level of wage.

“But we will look forward to the games, and hopefully we will improve and get results.”
