Messi signed with PSG after his contract expired at Barcelona
Brazilian football legend Ronaldo has fired a warning shot at Paris Saint Germain, claiming that simply having Lionel Messi in their side doesn't guarantee them success in the Uefa Champions League.
Messi signed with the Ligue 1 outfit after his contract expired at Spanish giants Barcelona, giving hope to the Paris fans of their maiden Champions League silverware.
"It's still too early to say who will win the Champions League," Ronaldo said in an interview with AS.
"I played for Real Madrid for almost five seasons, in the Galacticos team and I never won the Champions League. Winning is never mathematical, even if you have the best on your team. It also applies to PSG."
Messi previously won Europe's most prestigious competition four times with Barca.
