I agree with you. I think Barkley does have a lot of talent but the way he is being described is just not right. People are comparing him to a young Paul Gascoigne which is a bad comparison because he is some way behind where a young Gascoigne was. I've even seen it repeated a few times that he's like Gazza but with more pace so better. This is completely ridiculous. Barkley has more pace than Gazza but his touch is nowhere near as good. His main trick seems to be based around his pace, he knocks the ball past a defender and then races past them: and fair play to him it does work quite often as he does have pace and very good surge of acceleration. What he doesn't have is the close control that Gazza did, where he would take multiple touches and keep the ball with him while he went round people. So Gazza could get out of a tight situation from a standing start with two men on him and then take it round the oncoming defender. Barkley can't - Barkley can beat one defender when there is open space ahead of him but because he relies on knocking the ball ahead and chasing it, if there's a man in front it will get picked off. Also he tends to run down blind alleys and run in to traffic where Gazza wouldn't, he'd beat his man, get space then put in a killer pass. I don't see Barkley having that eye for a pass, he tries a lot of quick one twos and stuff but the radar is a bit erratic.
I'm not knocking Barkley here, and perhaps it's unfair to hold him up in comparison to a young Gascoigne because Gazza in his Spurs days was not a million miles off Maradona he was a genuine world class player, probably the last that England has produced, very few are of that calibre. The reason I'm bringing up the Gazza thing here is because that's the source of the overhype: this stupid Gazza comparison.
I fear that Barkley won't actually improve: like a lot of young English players he will burst on the scene with a lot of hype and then just play to the gallery, enjoy getting the roar of the crowd when he beats a man and then an "ooooh" and applause when the move fizzles out. He will get a big transfer and a big wage and then will just sit on his laurels and not progress, like Walcott did, like Wilshere did.
