Tottenham boss Harry Redknapp has saluted Gareth Bale as a player without a "weakness in his make-up".
Bale scored twice as Tottenham won 2-0 at Norwich to record their eighth win in ten Premier League games.
Redknapp insists only the world's richest clubs could afford the Welshman but clarified Bale is not for sale.
He said: "If we sell him, we've had it haven't we? It would only be a Barcelona, a Man City or a Real Madrid who would be able to pay for him."
Redknapp could not hide his admiration for the 22-year-old, who has now scored eight goals for Tottenham this season, as well as three for the Welsh national side.
The Tottenham manager added: "He's an amazing player. He's got everything, there's not a weakness in his make-up.
"He can head the ball, he's as strong as an ox, he can run, dribble and shoot. Most important of all, he's a smashing lad."
Bale joined Tottenham from Southampton in 2007 for a final fee of £7m but that price tag has soared in recent seasons with powerful performances in the Premier League and in European competition.
His hat-trick against Inter Milan in the Champions League in October 2010 thrust the Cardiff-born left-sided player into the world spotlight, but Redknapp reiterated that any approach from England or abroad would be rebuffed.
"They [Barcelona, Man City, Real Madrid] are the only ones who could afford to pay the transfer fee and his wages, but he isn't for sale.
"The chairman has said he isn't for sale. If you are looking to go somewhere you don't go and sell a player like him."
Tottenham are seven points behind leaders Manchester City, with a game in hand, and lead fourth-placed Chelsea by four points, also with a game in hand.
Despite his side's excellent run of form, Redknapp refused to be drawn on the chances of Spurs winning the league championship for the first time since 1961.
He added: "It's not impossible. It's very difficult but I never said we couldn't win the league. We have to just keep picking up points and see where that takes us."
Tottenham travel to Swansea on New Year's Eve, when the former Portsmouth boss hopes to have more selection options.
"When everyone is fit we are very strong," Redknapp added.
"Michael Dawson and Tom Huddlestone are on their way back and Jermain Defoe could be back for the weekend."
Redknapp has previously hinted that he is hunting a "special" signing in the January transfer window.
