I have a few ideas.
I think the sending off needs to be sorted out, i have tackled a player but got sent off 30 minutes after it happened.
I also think you should have the chance to appeal against your red cards in the be a pro mode.
I think other people have had some great suggestion the anger meter in particular is great, i think it be a good idea if you could argue with the ref or the players size each other up.
I also like the idea of seeing the manager and players on the bench and seeing them warming up.
I also wanted to say that the games are getting better each year and i can't wait for this one to come out.
