Take the point that squad sizes need to be the same for all teams. I would like to see the squad size reduced to 18 with any other players having to be under 21s. That would result in the situation where footballers actually play football, and give managers genuine team selection and system conundrums, not the current "which of my 6 international right sided midfielders shall I play this week". And most importantly it would give young players a real opportunity.
