Which youngster could emerge?

BBC Sport's experts have been considering which young players may become big names this season.

BBC Sport's Simon Stone gives his verdict on Chido Obi-Martin:

Arsenal [where Obi-Martin played for the last two years] believe they made a fair offer to the 16-year-old forward, who has represented both England and Denmark at youth level. But he has decided to join Manchester United.

The reasons for this will be debated but Obi-Martin has proved himself to be lethal in youth ranks – he scored 10 goals in a single game against Liverpool Under-16s when he was 15.

It will be fascinating to see how quickly he develops and whether he gets a chance in the EFL Trophy and Uefa Youth League. If he does well there, might we see him on the United first-team bench at some point?
