Lionel Messi in training

Lionel Messi says he is in a good place as he prepares for the World Cup.

Argentina will play Saudi Arabia in the first game of the tournament on Tuesday.

The Ballon d'Or winner had a chance to win the World Cup when Argentina lost in the final.

"This is probably my last World Cup, my last chance to achieve this great dream that I have."

Despite the tournament being in the middle of the club season, the Paris St-Germain forward feels fit and ready.

"I think I'm in a great moment, both personally and physically, and I don't have any problems," said Messi, who did light training away from his team-mates on Saturday.

I was told that I trained differently. There is nothing strange about it being because of a knock. It was merely a precautionary measure.

Messi broke his international trophy duck last year when Argentina won the Copa America, his first trophy as an international player.

"It's a beautiful thing that many people outside of Argentina want us to be champion and that it's mostly because of me," said Messi.

It's another example of the love I've received around the world, and I'm thankful for it.

I'm not sure if we arrive better at the World Cup than at other tournaments, but we just won the Copa America and that makes us sad.

It makes us enjoy ourselves and not worry about the national team's results.

Argentina will play Mexico and Poland in Group C.
