Definitely a different stadium to the 'World Arena'. Perhaps a use for the billions that lots of players have built up in cash? Interesting to see where they go from 'World Arena' in terms of naming... 'Intergalactic Bowl'!!
We've made lots of suggestions on academy improvements over the years. I suspect it will be something fairly simple, maybe the option to select 3 or more youth players when they're ready, for different amounts of tokens. Like we had when we got players for the National teams. My preference would be a system where we were able to select which positions were trained at the start of each youth cycle. Would require some planning but at least you'd get players in the positions you needed.
