Belgium take on Japan on Monday in an intriguing Round of 16 tie at the World Cup.

The star-studded Belgium side have plenty of players who will be looking to lead their side into the quarterfinals, while Japan’s leading lights will want to pull off an upset that could be the biggest result of their careers.

Here’s a closer look at the key battles which will decide this game.

Eden Hazard vs Shinji Kagawa

It’s somewhat surprising to see the player who’s been so grumpy at Chelsea cut such a smooth figure as Belgium captain. He’s a visible leader of this side, most notably with how he demands more out of Romelu Lukaku.

It helps when you have his quality. Hazard looks dangerous every time he gets on the ball at the World Cup. Japan will have their hands full.

A few years ago, when Hazard and Shinji Kagawa moved to the Premier League in the same summer. it would have been feasible to ask who was better. The trajectories of their careers since then render that question moot, but the Japan playmaker excels at his craft.

Japan’s hopes of an upset rest on Kagawa’s shoulders

Romelu Lukaku vs Yuyo Osaka

The form Lukaku has been in for his country is unreal. He’s scored 16 goals in his last 11 internationals, including four in two games at the World Cup. Along with Harry Kane he’s now the frontrunner for the Golden Boot. Japan’s defence has been somewhat shaky at this tournament, and Belgium’s lead striker will be hoping to feast upon it.

Yuyo Osaka isn’t in quite the same form, but he’s been crucial to Japan’s progress in Russia. His goal gave them a vital three points against Colombia, and he was a handful for the Senegal defence in a 2-2 draw. Belgium’s defence hasn’t quite been tested at this tournament, and Osaka might be able to take advantage of that.

Thomas Meunier vs Yuto Nagatomo

Thomas Meunier’s form at wingback for Belgium has been a vital part of their success at the tournament so far. He was one of the best players at his position in the group stage, and he adds another dimension to the Red Devils’ attack. Only Hazard and Kevin de Bruyne have more key passes for Belgium at the World Cup.

Like Meunier, Nagatomo has emerged as one of the most reliable performers for his side. His crossing ability from left-back is a key aspect of Japan’s attack. More importantly, he provides a collected, calm presence for his side, which could be crucial in a crunch game like this, especially given the calibre of the opposition.
