I believe Moggi was talking about "the best of the best" when he said that no superstar will join a serie A club this summer. Guys like Messi, Ronaldo, Vidic, Rooney, Xavi, Iniesta, Torres, Kaka. He said that unlike last year, when the superstar Ibrahimovic came to Italy, or the previous summer when Inter bought Eto'o, this year there won't be such top signings.
If I understand this correctly, Moggi doesn't exclude signing top players (for example...Higuain, Nasri and the likes). He only excludes the very best.
Shame though, since most of us still remember the recent past when Italy was #1 destination for the best players in the world.
