Ryan Sessegnon shouldn’t be as good as he is at 17. The Fulham left-sider might have been taking his A-Levels this year. Instead he's one of the best players in the Championship.
When you watch him it’s easy to forget his age; he looks as experienced and as composed as anyone else on the pitch.

When he was named Championship Player of the Month for January, he wasn’t allowed to collect his award as it was sponsored by Sky Bet. At 17, he’s not old enough to gamble.
Fulham did well to keep hold of him in January, but it may be a different story come the summer, especially after he starred in the Cottagers' Championship play-off semi-final win over Derby County.
But just what makes him the hottest teen outside the Premier League right now? Watch the video at the top of the page to find out.
