I guess a 400k loan with him 'only' earning 1 million is quite a good deal from our side (providing at least one striker leaves). The option to buy at 18 is very high, but we all know what will happen. We won't take up the option, Marotta will offer 10-12 in summer (if he plays well enough) and we'll sign him at around that price.
I will keep an open mind on Osvaldo, and while I don't rate him very highly, I think the deal is quite good
