Cristiano Ronaldo is confident he will have no problems adapting to life in the Spanish Primera Division following his world-record move from Manchester United.

Ronaldo was officially presented as a Madrid player on Monday after passing his medical earlier in the day and then putting pen-to-paper on a six-year contract with the Spanish giants, completing his record-breaking £80million move.

"I am just so happy. For me, I have made my childhood dream a reality, which was to play for Real Madrid," he said.

Ronaldo's move to Spain brings to an a six-year spell with United in the Premier League, during which time the Portugal international won a host of team and individual awards.

Much is now expected of the reigning FIFA World Player of the Year at Madrid, especially as he now carries the tag of the most expensive player ever, but the winger insists he is ready for the challenge of testing himself in a new environment and a new league.

"I expect a different league of course," Ronaldo said. "I played six years in the Premier League and it's very difficult.

"It's faster and players are stronger. It's very competitive here as well. It will be interesting. I look forward to enjoying La Liga.

"I think I'm ready for this challenge. I eat good. I sleep good. I drink good. I think I'm ready for this league.

He added: "I am sure that I will be able to adapt no problem. I have some Spanish skills, Spanish language skills, I am compatible with the life here and I am sure that I will make very good friends here."
