Yes, of course. Where there's an option for up to 100 players to be on a team, there's potential for some of those players to be adult and therefore online chat could well be inappropriate or worse for youngsters. Firstly, make an agreement with your child before s/he even starts on the game that play will only be (say) 5 games long.
Each game is 20 mins, so you can return at this set time or just before and remind that this is the last game for the day and switch off at that game's end. Also, go into Settings, on into Parental Control, and set what age levels your child is allowed to play. Best to set so that games for older players don't show up as options. also best to set all this when you are alone!!
