Hello Louise, just moved here with the family.  We have joined Dubai exiles rugby club for my son who is 8, also as they have a netball team for my 7 yr old daughter.  We need a football team for my son who is used to playing in a league, all I can find is coaching.

Thanks for contacting Expat Echo Dubai.
There are a few leagues as football is very popular and active throughout Dubai.  These leagues include  JFL League http://www.esportsuae.com/page/junior-football-league-j-f-l-  andIFA Leagues https://www.ifasport.com/what-we-do/football-leagues.aspx
