It's sad to see him think that he needs to move to a ''big'' club but honestly it is true and it's not about us as much as it's about the league we are in.
I also don't want to go through the discussion about how we are financially inferior to the current big ones (Chelsea, City, Utd, Madrid, Barca, Bayern, PSG) and how his current salary wouldn't be enough for the ball boy in one of these clubs.
But let's face it, if he wants to win the UCL then he needs to leave, if he wants to win the Ballon D'OR then he needs to leave because there is no way a Serie A player is winning that for the next 10 years at least unless there is a Champions league title which is not coming to Italy anytime soon.
Yes he needs to leave, back in the day when we sold Zidane we were much more powerful financially and had a much stronger reputation and it was normal for us to go into the UCL expecting to win, yet we still sold him, today we have nothing except for the hopes of reaching the QTR final.
