TOP 10 PLAYERS to watch at the World Cup.

LIONEL MESSI, ARGENTINA

Messi does not need a World Cup trophy to validate his greatness. The goals, assists, La Liga titles, Champions League crowns, records, awards and breathtaking highlights are ample evidence of his epic impact on the sport over 13 years.

Nonetheless, there is a missing piece to his incredible body of work: a major championship for his country. The 2005 Under-20 World Cup and 2008 Olympics (U-23s) were age-restrictive competitions. The two tournaments that matters most are the World Cup and Copa America, which decides South America’s best.

The World Cup has left him with two quarterfinal exits and a 2014 championship defeat settled in extra time. Copa America has offered three runners-up medals (two on penalty-kick tiebreakers) and a quarterfinal setback.

CRISTIANO RONALDO, PORTUGAL

If Messi is the best player in the world, Ronaldo, 33, is barely a step behind. Soccer fans of the modern era don’t realize how good they have it watching two of the greatest in history perform weekly — and several times each season against one another in Spain.

While Messi mesmerizes with speed of foot and thought, performing skills with elegance and efficiency, the bigger and stronger Ronaldo obliterates defenders with a combination of cunning and power. He is also a master in the air.

He orchestrated Portugal’s European Championship conquest in 2016, but the World Cup results have declined since his 2006 debut: fourth place, round of 16, group stage.

NEYMAR, BRAZIL

In 2014, Brazil’s hopes of winning the championship at home all but ended when Neymar fractured a vertebra in the quarterfinals. (Even with him, Brazil probably wouldn’t have avoided semifinal elimination against Germany.) This summer, his right foot is in focus.

He has sufficiently healed from a fracture suffered in February while performing for Paris Saint-Germain. But without any competitive matches until the World Cup tuneups, Neymar will need to find his fitness and form in a hurry. Brazil has assembled a mighty roster and, with an influential Neymar, a sixth title is well within reach.

MOHAMED SALAH, EGYPT

The best players in the world come from Europe and South America, occasionally West Africa. They certainly don’t come from North Africa. Until now.

In his first campaign with Liverpool, Salah set the Premier League’s single-season scoring record with 32 goals. He had 12 in nonleague competitions for a total of 44 in 52 appearances — an astounding rate for someone who didn’t play much at Chelsea in 2013-15 and was a modest scorer at Roma. He was also instrumental in Liverpool’s unexpected charge through the Champions League.

DAVID DE GEA, SPAIN

Goalkeepers tend to peak at ages older than outfield players. At 27, de Gea is just getting started but already finds himself at an exceptional level.

Never mind his blunder in a pre-Cup friendly against Switzerland. De Gea was the best keeper in the Premier League this season, probably the best in Europe and the world. Manchester United supporters voted him their most valuable player. His 18 shutouts in 37 league matches earned him the Premier League Golden Glove award. In December, he equaled a league record by making 14 saves during a 3-1 victory over Arsenal.

EDEN HAZARD, BELGIUM

With his tight footwork, rapid acceleration and panoramic vision, the Belgian winger’s style has drawn comparisons to Messi’s. Granted, Hazard is not as searing and ruthless, but when he tears into open space or takes on defenders, he raises anticipation like few others in the game.

Since joining Chelsea from Lille in 2012, Hazard has scored 89 goals across all competitions, earned the club’s player of the year award three times and been part of two Premier League championships. In early 2008, he debuted with the national team at age 17. In the 2018 World Cup qualifying campaign, Hazard scored six goals in eight appearances.

ANTOINE GRIEZMANN, FRANCE

While most of the world stars arrive at the World Cup from famous clubs such as Real Madrid, Barcelona and Manchester United, Griezmann comes from an organization rich in tradition but lighter in aura. Atletico Madrid has been a wonderful platform for the left-footed attacker, who has averaged 20 goals over four seasons since arriving from Real Sociedad.

His national team debut did not come until March 2014, a few weeks before his 23rd birthday. Three months later, he was starting in the World Cup. At the 2016 European Championship, he won the Golden Boot by scoring six goals and was named player of the tournament.

JAMES RODRIGUEZ, COLOMBIA

In 2014, the Colombian attacker won both the Golden Boot with six goals (plus two assists) and the hearts of Brazilians when the emotions of a quarterfinal defeat to the hosts were too much to control. Rodriguez had played with joy and zest — traits appreciated by audiences on site and around the world.

The sterling World Cup performance led to a mega-transfer to Real Madrid from Monaco, but after a quality first season in Spain, he labored to earn regular starts. This past season, Rodriguez was on loan at Bayern Munich.

THOMAS MUELLER, GERMANY

Although his scoring totals at Bayern Munich have plummeted the past two seasons, the hybrid attacker cannot be ignored in major international events. Mueller is not technically or physically imposing; he simply knows how to pocket goals.

Mueller scored five times at the 2010 World Cup in South Africa and five more four years ago in Brazil, including a hat trick against Portugal. His total (which has come in 13 matches) ties him for eighth on the all-time list. (Pele posted 12 goals in 14 games; the all-time leader, Miroslav Klose of Germany, scored 16 in 24.) Mueller has also scored nine times in World Cup qualifying and 12 in European Championship qualifying.

GABRIEL JESUS, BRAZIL

Looking for a young, breakout star? This 21-year-old striker from Premier League champion Manchester City is a suggestion. Four years ago, he was painting World Cup themes in the streets of a Sao Paulo slum. These days, the residents of Jardim Peri have honored him with a 112-foot-tall mural depicting his goal celebration.

In his second season in England, Jesus scored 13 goals in 29 league appearances (19 starts) and 4 in 9 Champions League matches. Upon arriving at Brazilian training camp, he held a slight edge over Liverpool’s Roberto Firmino for the starting job in the World Cup opener against Switzerland.
