1. "formations" unusable. Different formations should have different palyers assigned, orders, subs, etc...
2. young players (from academy) cost too much - you can buy better for less tokens
3. cant see player rating during match - only on HT will be enough too. I can see that player played with 4 after the match - if i knew it earlier i would make substitution.
4. "vs" button showing match preview/standings is good. But it will be nice if there are some kind of all time statistics between clubs. Especially for higher levels - i have played with some clubs in more than 1 competition (I'll add this to suggestions too).
5. chat/messages at least with friends
