I don't think Elkann has given a damn about reviewing Comolli's resume. I wouldn't be surprised if it was Platini who suggested hiring Comolli. The fact that he failed at Fener doesn't really surprise me as Turkey is a completely exotic place for a Frenchman. What's more, looking how these clubs suddenly found a goldmine it suggests some shady doings.
You guys keep comparing John to Gianni but these are two completely different eras. L'Avvocato main focus was Italy and FIAT while Elkann runs a global fund which is much bigger and more powerful globally.
On a side note, I have recently read a book about Agnelli family and found an interesting thing there. You probably are familiar with the conflict of Margherita de Pahlen (mother to Elkann, and Gianni's daughter) and the rest of the family. What I read is that Antonio Giraudo, member of the famous Triade with Moggi and Bettega, actually persuaded her to reject previous agreements regarding the inheritance from Gianni and start a new trial against John and Gianni's accountants and lawyers who represented his will after his death (for example Grande Stevens, ex Juve president).
That throws some light on why Elkann didn't support the Triade in their trial.
