Montolivo out means we'll go after a midfielder, which became our first priority. I still think that we should buy a CB first (and Rami was great at that last season), unless we want to suffer another year with Zapata-Mexes or, God forbid, Zapata-Bonera.
Yes, FM has an option for online play: everybody picks a team (one team per player, no duplicates), there's only one Ronaldo, one Messi, one Matri - every player can make offers for them and buy them, but there won't be two Ronaldos for two different Real Madrid. Only one Ronaldo, playing in one team.
It's pretty fun, as long as everybody's internet connection is stable and fast, and the admin remember to save a lot, usually right before and after a match. Otherwise, prepare to cry a lot after seeing Lewandowski score six goals against Tottenham minutes before FM crashes, obviously after nobody saved the game.
