At 15mil it's worth a punt, but I don't see what the fuss is.
His end product and final ball isn't great, but that can improve with age, though I don't see great technique, and that's something you either have or you don't.
Players like Messi, Ronaldo, Ronaldinho etc... Always had the technique, what improves with age is the consistency, and how they apply their techniques within games.
OK, he has insanely frightening speed, but he uses a kick and run style to beat a man, which would work great on the counter, but against a deep organised defense it will be practically useless.
And if we get back to the level where we want to be, I assume more teams will be using a deep back line against us.
Just for comparison look at the video in the turkish Messi thread, and look how his dribbling allows him to beat multiple players with only half the speed of this lad, just by using quick changes of direction.
This is the kind of dribbling that unlocks defenses.
But again, at 15mil it's worth a punt.
Also one last thing, posters saying these kind of punt signings are what Sir Alex used to make, need to realise that back then we were the most dominant team in the league, which made making punts easy, and risk free.
