It's very interesting because we seem to have loads of that type of player (ball carriers) in our U-21 teams over the last couple of years or so - Hannibal, Iqbal (wonder how he's doing in the Netherlands), IHA, Mainoo, even Gore, seem to be a lot more comfortable on the ball dribbling and carrying the ball than any of the first team midfield (not saying they're better players mind).
Seems like a conscious choice, so one wonders why that hasn't really translated to the seniors.
Interestingly Mount is the one I think is the best dribbler of our current senior set, even if he hasn't shown it yet.
