Chelsea vice-captain Cesar Azpilicueta is part of a strong Spanish squad that has been at the top of world football since 2008.
The 28-year-old is the only Chelsea player to make the World Cup squad, and he is hoping for an excellent tournament in Russia.
He told the official Chelsea website: “In the group stage, we have just three games, so there is no room for mistakes.
“We start with Portugal and it’s going to be tough, they are the reigning European Champions of course. But I think that could actually be a good way to start, playing against the best and if we can get a win and start strong, then it could set the tone well.
“We have a lot of preparation before the World Cup from when the season finishes and we have a lot of time waiting in hotels and things like that. You have to try to keep your mind clear and focus on the task in hand and to ensure you are in the best possible condition ahead of the first game.
“It’s exciting to be at a World Cup and we all can’t wait to get underway.”
