Both are competing at the World Cup this year in what may be their final chances to win football's ultimate prize.
Messi is, however, back in the mix at Russian Federation 2018 and will be desperate to get his hands on the top prize and enhance his standing as an all-time great. He's a guy who surprises me every day. A strong showing by Ronaldo in Russian Federation, capped off with lifting the trophy, would nearly certainly clinch it for him. Messi came so close to emulating the great Maradona and INSpiring Argentina to a World Cup win in Brazil in 2014, but his career for La Albiceleste has been tinged with disappointment and frustration.
But when the prodigal son returned they won 21 points from the next 10 matches, with Messi scoring a hat-trick in the final game against Ecuador.
Last year's Copa America final defeat to Chile, in which Messi missed a penalty, was the latest bitter disappointment in long list of anti-climaxes.
Alejandro Sabella, who was in charge in Brazil four years ago, believes Argentina's progress has been impeded by the absence of "the more cerebral players" they frequently used to produce, playmakers such as Pablo Aimar, Juan Roman Riquelme, Juan Sebastian Veron and Ariel Ortega, that could be to Messi what Andres Iniesta has always been at Barcelona.
Meanwhile, NAIJ.com had earlier reported that Argentina pulled out from their worldwide friendly against Israel.
It is a tough task to pick just one team as favourites.
Two weeks ago, the Independent released the results of a poll that stated that despite the claims of Messi's throng of young fans, Edson Arantes do Nascimento, known to the world as Pele, is still considered the best player ever.
These qualities make him the bane of numerous opposition's defence as he alone, can wreak havoc and create chances for his team, especially from the flank which could compliment the brilliance of Messi and the talents of the other strikers.
"You wouldn't expect Messi to have said that", Arnason said.
Like Messi, Ronaldo has put his national team on his back on countless occasions in the past.
