Key Players

Toni Kroos (Real Madrid) - Germany's new leader, Kroos keeps the side ticking from midfield, where his intelligence, precision and composition on the ball inspires teammates going forward.

Messi (Barcelona) - Doubted by fans, yet the five-time world player of the year delivered. Argentina would not be going to Russia without his goals and leadership. Turns 31 during a tournament that could yet crown his career.

Kevin De Bruyne (Manchester City) - Overshadowed Eden Hazard at the 2014 World Cup, he has only grown in stature, especially since his move to City and his more withdrawn position on the pitch.

Neymar (Paris Saint-Germain) - Should be at the peak of his game aged 26 in Russia, the forward will have his best chance to overthrow Lionel Messi and Cristiano Ronaldo in best player awards if Brazil wins.

Lewandowski (Bayern Munich) - Already Poland's record goal scorer, he scored a European-high 16 goals in qualifying.

Ronaldo (Real Madrid) - At 32, Ronaldo is no longer the goal machine he once was. Key to success in Russia could be how he is managed by Madrid, and can be rested in less significant games.

Raphael Varane (Real Madrid) - The three-time Champions League-winning center back has the difficult task of marshalling a vulnerable defense.
