After guiding the league leaders to a 2-0 victory over QPR on Saturday, the veteran Welshman looks set to go down in history as the Red Devil's greatest ever player
The duo were both on the scoresheet on Saturday in the 2-0 win away to QPR, in what was Giggs' 999th professional appearance for club and country, and the Brazilian right-back says that as well as being one of the top players at the club, the Welshman is a big help to the young members of the team.
"He is an unbelievable player," Rafael told reporters. "You can only say good words about him: He plays, he scores, he assists.
"He is the same in training, he just loves to play the game. He is one of the top players that I have played with.
"He gives us experience, confidence, and when you are feeling bad he comes and helps you, especially young players.
"Sometimes a young player finds it tough going and he helps them. He shows them how to do it. He knows it from playing 22 years. He pulls the player aside. He spoke to me a lot when I was young."
Giggs' goal late in the game at Loftus Road sealed the win for United that temporarily put them 15 points clear of rivals Manchester City in the title race, until Roberto Mancini's side defeated Chelsea on Sunday.
QPR manager Harry Redknapp echoed Rafael's sentiments, stating that Giggs is "top-class", and his longevity sets him aside from others.
"He is top-class, an amazing player," Redknapp stated. "It's very difficult to think of anyone with his longevity, especially now in today's modern football with the speed of the game."
