Paris Saint-Germain chairman Nasser Al-Khelaifi isn't the first man to be enchanted by the idea of Champions League glory. Roman Abramovich, among others, can attest to that.

It took the Chelsea chief nine years from buying them to seeing the club crowned kings of Europe, in 2012 against Bayern Munich. So far, Al-Khelaifi has been at PSG since June 2011 and in five Champions League campaigns, they have got as far as the quarter-final.

Once the dust settles on the exit at the hands of Real Madrid and Al-Khelaifi assesses how PSG compare to the rest of Europe's elite, he may feel his side have more similarities to Celtic than Chelsea. And that is there where the magnitude of winning Europe's elite club competition becomes startlingly clear.

PSG, like Celtic, are the best team in their league by a distance. They largely have the picking of all the best players at the other sides around them. They have a super stadium and an ardent fanbase. And every season, they fail to meet their expectations in Europe, often getting picked off by a bigger bully in a different playground away from the comfort of their own division.

The money PSG have can even put Chelsea in the shade. When Kylian Mbappe's loan from Monaco becomes permanent for £166million in the summer, the Qatari Sports Investment company that own the club will have spent over €1billion (£896m) on players. That simply demands a better return than the quarter-final.
