I don't think anybody is saying bale isn't a very good footballer or anything. He's one of the best true wingers (none of that playmakers on the wing like silva) in the world clearly at the moment. However, he is a long way away from the very top players like Ronaldo, Ribery, even nani from 2009-2011. He just isn't technically good enough to improve so drastically because he is 24 currently, not like he's a young player anymore. Maybe he will improve a little bit, but there won't be any ridiculous improvements.
He's obviously in great form now, but go back around 1 month and a half back, and nobody was even mentioning him. Now that he's scored in a few consecutive games he's worth 50million and the hottest prospect in football? feck that. For a winger, he gets a very low number of assists, and no matter what you say about strikers not putting chances away, he has to do better then 2 or 3 a season. That's just really poor for a winger. Also, can't understand some people calling him a prospect? Like I said, he's not a young winger anymore. He is pretty close to his prime, and the way his game is, you can't see him imporving all that much. I could see him getting more consistency and adding assists to his game, but he'll never be at the level of Ronaldo, or Ribery, or what robben was a few years ago. He simply doesn't have enough in his locker to get to that level.
On the comparisons with other youngsters, if people watch gotze, or if he was English and in the premier league, the prices touted for him would be well above 40m, no question about that. His ability on the ball, vision, awareness and football intelligence can't be trained and its something bale could only dream of having.
Neymar is definitely overhyped as well, but to call bale a better prospect is just wrong. Neymar is one of four players to have ever scored 100 goals before the age of 20. The other 3 are maradona, pele, and Ronaldo. Are you seriously going to put bale in his company? He's probably a better player right now because he is four years older and has played in a much better league his whole career, but he doesn't have anywhere near neymars talent on the ball.
Like others have said, he's having a good season and is probably in the form of his life, but look at some other players this season like mata, who has one goal less then him, and plenty more assists. Mata has scored 16 in all comps and asissted 18. We're are the talks of his form, or the prices of 40 million for him? One thing is for sure, I'd much rather spend that on mata then bale.
The only reason bale is valued so highly is because he is British. Very good player, in great form. But a world class player? I don't think so.
