I think he will not extend. He already proved his doubsters he had stills some fuel left. maybe not in the CL, but he has done wonders for us in the serie A,,and more than compensated for what we paid.
If he goes when his contracts terminates...he will still have something to give to Boca. Staying with us makes no sense for him anymore IMO. We surely are not CL contenders and he already ripped serieA a new one.
But if he goesthere, he will have something to play for, to demonstrate. And he will be spirited to do it.
IMO he is a goner.
