Dowman looks pretty insane. Born on New Year's Eve 2009 so he is still not even 15 and a half.
He keeps doing this nonsense at U18 level and if anyone says you can't read much into it, I will agree.
But then Dowman also started turning out for the U21s late last year, when he was still 14. So he has already played in PL2.
You would think he couldn't feature with the first team squad much until 26–27, but he might get a run out at some stage and will probably be training with the seniors too.
