I'd rather have 37 million pounsterling cash rather than 30 + Crespo. I mean Crespo is good, but I hardly think he can be successful at Juve.
And I doubt Parma would want a Crespo+cash deal for Gilardino :D
If we sign Crespo then Milan will go all out for Gilardino. The only real strategy IMO is getting Crespo and letting him go to Milan. So we can get Gila, although I'd think that Milan would refuse anyways and go ahead with Gilardino.
