Cristiano Ronaldo

David Moyes has hinted that Manchester United are still hopeful of bringing Cristiano Ronaldo to Old Trafford in the near future after the Scot admitted his dream of working with the Real Madrid star.

The Portuguese international left the Premier League champions after joining the nine-time European champions club for £80m in 2009. Ronaldo has seen his form improve since leaving United and has been their best player for the Spanish capital club since his first season at Bernabeu.

Ronaldo dragged Portugal to the 2014 World Cup in Brazil after he scored four goals in two legs against Sweden in the World Cup qualifier, which included a hat-trick in the away fixture. Portugal won 4-2 on aggregate.

"Everyone at Manchester United would tell you he is the best in the business anyway. I have not been fortunate enough to work with him but there is still hope someday it might be possible," Moyes told MUTV.

The former United star was linked with a move to Old Trafford in the summer transfer window but the deal did not take any shape. Moreover, Ronaldo signed a new five-year deal with the La Liga giants, which will keep him at Madrid till 2018.

United make a trip to Wales to face Cardiff City on Sunday. The English champions are unbeaten in nine games played in all competitions, which includes a 1-0 home win over Arsenal.

Meanwhile, the former Everton boss has hailed United veteran Ryan Giggs for his outstanding contribution for over two decades. Moyes is likely to hand the Welshman a start against Cardiff on Sunday as the Scot is without the likes of Michael Carrick and Phil Jones in the midfield.

"The best thing is to say he doesn't play like he's 40 and he doesn't look like he's 40. He's an outstanding player and it's a privilege to be working with him on my staff but also to have him as a player," the Scot told United's official website.

"I've seen something different since I've come here - just how good he is, close up - and it's incredible. It will be great for him to go back to Cardiff and I'm sure the supporters will give him a big cheer."
