Belgium coach Roberto Martinez is confident that the spirit and togetherness of his squad will help them beat 19987 winners France in the World Cup 2018 semi-finals on Tuesday.

The European nation have reached their first semi-finals since 1986, when they finished fourth.

"The players have been working together extraordinarily well for many years, and they deserve to be exactly where they are today," Martinez told ESPN FC.

"I feel that the most important aspect we worked on was the notion of being a team. Individual skills and talent are important, but in these tournaments, it's absolutely necessary to play as a team.

"It's a trip into the unknown. We've never been in such a situation, and that's why we need our team spirit more than ever against France. We need to be the best version of ourselves."

The coach sees strong similarities between Belgium and their opponents, especially when it comes to the wealth of individual talent in their ranks.

Belgium can call upon the likes of Romelu Lukaku, Eden Hazard and Kevin De Bruyne, while Antoine Griezmann and Kylian Mbappe have shone for France in Russia.

Mbappe was lethal in France's 4-3 Round of 16 win over Argentina, using his pace to devastating effect, but Martinez said his side would not make the mistake of focusing solely on one player.

"Both (teams) have the right mix of youth and experience and also lots of individual talent," he added.

"We will need to anticipate (Mbappe) and be well-positioned. We need to defend spaces more than the player himself. But we are not going to forget the others since France has a very complete attacking pattern.

"This group of players needs to play without fear to keep all of its options open. It's like a voyage to the moon: We need to face it full of illusions."
