My idea.8 German teams 18 Championship teams.
Edit over 6 of the 8 incomplete teams in other leagues A except two of the Russian teams Rubin and CSKA.Then adding to Bayern and Wolfsburg already done add Werder, Hamburg, Schalke, Dortmund ,Bayer Leverkusen and Stuttgart.
Of course Konami patch if it ever arrives could update the incomplete teams but is probably unlikely.
Also alot of the players for these (german) teams can be unlocked or an in national teams.Its best for realism in the master league to have a second division of English teams (if your playing an English league) otherwise you have to mix nationalities and that looks odd it means more work of course but the end result will be great!
So top 18 championship teams Newcastle, Middlesbrough, West Brom, Sheff Utd, Preston, Cardiff, QPR, Derby, Nottm For, Leicester ,Watford, Coventry ,Reading, Sheff Wed, Ipswich, Swansea, Bristol City and Crystal Pal.
Could also include Blackpool (whos league position deserves so) or maybe Barnsley/Plymouth or perhaps Leeds?
Could reduce to 14 championship sides and add 4 scottish teams to master league and then include more German/Russian/Austrian/Brazilian sides but I think 18 would work best and as an Ipswich fan I am sure you want you team, in a proper championship (well as near as can be)Rosh?
Great option file so far by the way thanks for all your hard work.
