Sevilla and Leverkusen made the best bit of business (in terms of value for money) of all the clubs you've listed in my opinion.

Also, one of Schweinsteigers old clubs (TSV 1860 Rosenheim) confirmed that his fee wasn't € 20+ million, but around € 9m.

Inter also loaned Alex Telles from Galatasaray with an option to purchase.
I would continue but I don't have the computer. I enter footyroom from my phone for 2 or 3 months.

Holy Crap Monacao earned a lot of Money!! With this they can spend big in the winter transfer alongside Sevilla and Arsenal.

City on the other side should try to sell or loan their youngsters so they can develop well in the future. You cant Just rely on buying superstars.

Wenger is the only man I would probably give my credit card.

@rayrex Madrid and City seem to do fine with it.

Actually they can, waiting until the youngster became consistent may take time and cost trophies for such demanding clubs. But if the youngster is already world class, its another issue...
