So Ronaldo was willing to cut his salary but then asked for a transfer to Real Madrid. Convenient.
Also, Nesta's move to Milan was shady as fuck. Nesta didn't want to leave Lazio anyway, it's like Totti being forced out of Roma, you just cannot envisage it.
As for the timeline.
Inter signed Cannavaro on the 7th of August.
Inter signed Gamarra on the 18th of August.
Milan signed Nesta on the 31st of August.
After a little while, this happened:
31/08/2002 - 23:25MILANO - L'attaccante argentino Hernan Crespo è dell'Inter. Si sta definendo in questi minuti il trasferimento di Ronaldo al Real Madrid. In breve tempo i dettagli e i commenti sull'operazione.
We signed Cannavaro exactly because Lazio would not sell Nesta to us. I guess they wanted the duo after all so that's why Gamarra is part of the discussion. We already had Materazzi and Cordoba who were quite good though. And Adani was signed earlier as well for backup.
