Well, the guy who made it actually never finished it, for example in Serie A only Juve, Inter, Milan, Roma, Lazio & Parma have the 2000-01 players in them. The other clubs are present-day (and frankly pretty easy to beat). Also, he forgot to erase certain present day players so there are a few who "time traveled", like Giaccherini, Gabbiadini... and you have to deal with Conte (as a player) being banned for the first several months because the database still has him as being under a global ban.
So it's not the most realistic thing ever, but since I got a little bored of my present-day Inter save, I decided to try this mod with Juve & just make a superteam that destroys everyone else for fun. FFS, there are child versions of Messi & CR7, I bought them both.
Casillas
Zambrotta - Nesta - Cannavaro - Pessotto
Conte - Ambrosini
Giaccherini - Zidane - Del Piero
Inzaghi
is generally my starting XI. Except for Giak, everyone is at the age they were back then. But I've developed CR7 enough now that I think I will replace Giak with him from next season. And Pessotto is retiring at the end of the season I'm in so I have a regen to come in for him.
