I reckon going flat out he may be the quickest out there.
He only looks in 3rd gear and he's still smoking quick players.
I did sprint at a decent club level, not saying I'm an expert but I have a good gauge of potential speed just on the eye test.
I think there's a few that might have slightly quicker acceleration over the first few yards. Not sure there's any that'd beat him once he gets moving, which is why his recovery runs when he has space to run into look insane.
I don't bother with stats, there's too many factors on a football pitch in clocking players top speed and make it mean anything.
He's even faster than he looks but he has such a relaxed running style. Where as someone like Walker, Traore etc were clearly putting 100% into their sprint and can look like they're going faster to the eye.
In my opinion, with my little bit of experience, I'd say he would beat prime Walker over 100m, but maybe not over the first 10 or so.
I'd back him to beat any player today over 100m actually, if he really pushed it.
But really, speed is nothing without the intelligence to use it. Luckily he has both.
It's better to be slow and be able to read the play than be quick and using it to bail yourself out because you didn't anticipate the play.
The fact he's smart with that insane speed is going to make him absolutely formidable when he's even more experienced.
