I know it's not an easy job doing an db update, done some for myself a few times. I know it take days to complete, weeks if you have a job.
Why not do a more proper job anyway though, updating at least the top 10 leagues in the world? Now he has just updated teams like Real Madrid, Juventus and Bayern. The most boring teams that gives you minimum challenge. Apparently not even AC Milan.
Wikipedia has a maybe not complete but impressive list of transfers, categorized after country. Not making it easier, but smoother.
Maybe I'm the only one who likes to play with many different teams, like Lille, Hertha, Valencia, etc.
