Official as well, 40 million euros. So Zenit just spent close to 90 million euros in two players from the Portuguese league.
Well, at least it's good for the Portuguese balance of trade.
Holy crap, I just had a look at Benfica's outgoing transfers in recent years:
Coentrao €30m
Di Maria €36m
Luiz €25m
Garcia €20m
Witsel €40m
Ramires €22m
€173m for six players who cost less than €30m when signed I think. Wow.
And Porto:
Hulk €55m
Pereira €10m
Guarin €11m
Falcao €47m
Meireles €13m
Bruno Alves €22m
Cissokho €16m
Lopez €24m
Lucho Gonzalez €19m
€217m for 9 players.
So a total of €390m for 15 players from Portugal in three years. Once again, holy crap.
