Some suggestions.

1.- Brands for jerseys. To work as the Sponsors & TV Rights.

2.- More jerseys. With option for a third color for more personalizing.

Thought I had more ideas. But for now there are some.

1 - There will be very high cost of licensing fees for that.
2 - Home kits are automatically used for home matches, away kits also for away matches. If you want third kit, just swap it around before your match starts.

I think seeing how players perform (rating) in the match would be very good. I see them after the match, which is not useful at all..

This would help managers watching the match and promote importance of attending them..

How about chat with every manager in ur league, champion and cup who is online? I think this very cool when watching live match

Great idea, but there may be abuse of the chat..
