Olivier Giroud is determined to seize the opportunity and win the World Cup with France by beating Croatia on Sunday.

The Chelsea striker says there is a difference in the mentality of the French national team compared to that from two years ago when Les Bleus lost the Euro finals at home to Portugal.

"It's different. After the semi-final when we won against Germany we were a bit euphoric, whereas against Belgium it was different," he said.

"It's not the same feeling - we know we still have one game to win. There's that real focus and concentration to finish the job - that's why it's different. We've come a long way to get here and we don't want to waste this opportunity now.

"You can't win a World Cup on just talent. Talent alone is not sufficient. You need efficiency. The mental strength is 70 per cent of the job. If you're ready to work for your team-mates and each other with dedication and commitment then anything can happen."
