Ronaldo and Messi have dominated the annual award for more than a decade, with Kaka in 2007 the last time someone else won the prize.
Portugal midfielder Manuel Fernandes said Cristiano Ronaldo "doesn't look at all anxious about his future" as the Real Madrid superstar contemplates a possible exit from the Spanish giants this summer. "Salah is certainly one of them".
Ronaldo issued his praise and support after his injury against Real Madrid in the UEFA Champions League final, while hinting he has a chance at winning the 2018 Ballon d'or title.
"I hope his injury in the final in Kiev doesn't keep him out", Ronaldo told reporters on Monday, as quoted by KingFut.
The pair could potentially square off again in the last 16, if Egypt and Portugal make it past Group A and B respectively.
Global highlights: Bernardo has featured for Portugal in a range of competitions as he was chosen to play in the European and World Cup qualifiers, the Confederations Cup in addition to a number of worldwide friendlies.
"A defeat on the first day puts you in a bad way for the rest of the tournament so it's important to start well", he said.
The European champions play their Iberian neighbours in the 2014 Winter Olympics host city Sochi in the opening match for both nations Friday.
