Gunners boss Arsene Wenger met the Portugal winger three times in a bid to bring the player to north London.

But United gazumped the deal by entering negotiations and bidding three times what Arsenal offered for the recently-crowned 2008 Ballon d'Or winner.

This was confirmed by Ronaldo, who signed for United in August 2003 for just over £12million pounds, in an interview he gave with France Football.

"I came within a whisker of doing it," he said.

"Wenger is someone I respect a lot. He is very intelligent."

Jorge Mendes, Ronaldo's agent, added: "That is what happened. Everyone wanted Cristiano; Real [Madrid], Juventus, Barcelona.

"But only Arsenal and Manchester United attempted to take him from there [Sporting Lisbon] that season. The others wanted to leave him at Sporting at least a year."

It is widely believed Ronaldo's sensational performance in Sporting's 3-1 win over United in a friendly on August 5, 2003 convinced the English club to sign him.

But Mendes revealed a deal had been agreed before that friendly, adding: "Everything was in place before, since an agreement had been reached the day before the match."

Ronaldo has gone on to become arguably the world's greatest player.

Under Sir Alex Ferguson, who Ronaldo labels 'The Master', the 23-year-old has added deadly finishing to his repertoire of skills and tricks.

After five years at Old Trafford, it looked as if he was going to sign for Real Madrid in the off-season but he ended up staying at United.

"I don't want to return to that. I have already spoken a lot about it," he said.

"I am at Manchester United and I feel very good at this club. I don't want to create other problems.

"For two or three months, people have spoken more about this than about football and I don't want to talk about it any more."

Another uncertain period for Ronaldo at United came after the 2006 World Cup.

His Portugal side knocked England out of the tournament on penalties in the quarter-finals, but during the match he was involved in getting Wayne Rooney - his team-mate at United - sent off.

Ronaldo was seen asking the referee to dismiss Rooney and as a result he was given a hard time by the English press and fans the following few months.

But Ronaldo said: "If I had to do it again, I would do it again. I was defending my colours, my country.

"What I did on the day was normal. When I came back to England after the World Cup, there were all these people booing me. That made me stronger.

"It was a test of my character. I learnt a lot because of this."
