Good news for Serie A: Leonardo quits PSG.
So with him and Ancelotti gone, we might get an ease up on the exodus to Paris.
Will it really change much? The best serie A players might not end up in Paris after this, but they will still be bought by the richer teams. It's true that Mancini, Ancelotti and Leonardo are responsible for the purchases of Zlatan, Thiago Silva, Balotelli, Lavezzi, now Cavani etc., but with or without them, those players would have been gone, or, if they weren't in City and PSG, they'd have been in another rich team and bought these players nevertheless. Perhaps talents like Veratti would have still played in Italy, but that's about it.
It's actually better for teams like Milan and Napoli that these Italian coaches (and Leonardo) are in charge of rich teams, because they'd have sold their players anyway, but this way they got more money than they would have normally.
To sum up, with or without Leonardo in PSG, the best serie A talent will keep leaving the league and look for more money elsewhere. At least for the time being.
