Former Trinidad and Tobago goalkeeper Kelvin Jack believes modern football superstars Lionel Messi and Cristiano Ronaldo must win at least one World Cup to be considered the greatest of all time.

Over the last decade, the Argentinean and Portuguese superstars have been the standard by which players have been measured.  At the club level, both have racked up unprecedented accomplishments.

The duo is mostly at the top of the list for titles, scoring records, Ballon d'Ors, and various other metrics of success.  Internationally, however, their records, as it relates to trophies anyway, are less impressive.

On one hand, both have managed to lead their countries to continental cups, with Ronaldo and Portugal winning the Euro Championship in 2016 and Messi winning the Copa America with Argentina last year.

The World Cup, international football’s biggest prize, however, remains conspicuously missing on the decorated mantlepieces of both players after four tournaments. 

Having dominated their peers, and the current era, the absence of the coveted FIFA World Cup Trophy remains the only question mark in any comparisons between themselves and the men most consistently mentioned in the greatest of all-time conversations, Argentina’s Diego Maradona and Brazil’s Pele.

“If you want to compare Messi and Ronaldo to the likes of Pele and Diego Maradona, I believe you have to win a World Cup,” Jack told SportsMax.Tv’s IncaseYouMissedIt.

“Messi, make no mistake, this is a special player.  This is a player that has reached a level we probably have not seen before in football, but you cannot disregard the brilliance of Maradona and what he did in 1986,” he added.

“Fortunately, I’ve been able to see the career of Maradona and witnessing Lionel Messi’s career and witnessing Cristiano Ronaldo’s career but you have to win the World Cup.

Cristiano Ronaldo has of course won the European Championship, Messi has won the Copa America but that last step to winning the World Cup is what would possibly cement his place as the best ever.”

With Messi being 35 and Ronaldo 37, the tournament in Qatar is expected to be the final chance for both players.
