I'm suggesting to add team's Playmaker and Target Man

Also add game tempo (fast, normal, slow)

And if can, add Counter-Attack options :D

I think for game speed you can find in tactics ( mentality) attacking is more speed.  Defending is slow 

That's something different, game tempo more specific :D

Add player's height and dominant leg :D

Maybe not important, but can you add "Top Clean Sheets" for GK?

Add "Holiday Mode" for managers who think they can't login for several weeks

Ofcourse this will cost some euros, and I'm suggest 10-15€/month
