Are you guys sure that the difference between Oscar and for example Pastore is that huge to even consider expense like 40-50m? As for trequartista, Pastore will be available in the upcoming summer for 20-25m. Rumour has it that PSG would accept everything around 25m, because Argentinian is running out of contract soon. The question is if we are willing do splash out millions more on Oscar or we would rather have Pastore among our ranks.
For me, answer is obvious, that's why I think all this discussion about Oscar is pointless. If we want to purchase trequartista, Pastore is the easiest, the cheapest and the very best solution at the moment.
