For the first time since 2015, Real Madrid kick off their Champions League campaign knowing they are no longer holders of Europe's most-coveted prize.
Tonight, Zinedine Zidane's side face arguably their toughest fixture in the group in their opening match against French champions PSG, who were boosted by the return of want-away star Neymar at the weekend.
The Spanish giants head into this match unbeaten in La Liga but could struggle in Paris with seven first-team squad members absent. PSG are also heading in under-strength with their usual front three all unavailable.
With both teams boasting star-studded squads worth hundreds of millions of euros in transfer fees, it promises to be a fascinating encounter at Parc des Princes.
