Come on Pickle, the original poster wasn't talking that Messi never mentioned Cristiano on an interview, less if he is asked about him. He is clearly talking about Cris bringing Messi more often to the table, at times even as an elevation shot without not mentioning the little fella directly. That has been a tendency. I don't think that's just being nice from Messi, in his house he might have cursed Cristiano lots of times, yet in Public? Messi's approach it's different, maybe even more clever and at the same time if Cris wants to praise himself time and again? so be it, nothing serious.
And BTW it's more related to how Messi fuels himself and how Cris does it, and how both manage themselves when they are angry too. Messi would be a lot more vindictive, revengfull while in the pitch than in his public declaratiosn, he took the same attitude with Journos that trashed him time and again, at must I've seen him avoiding them, but not directly confront them. In the case of Cris, he chose not to confront him in that "arena" and that it's pretty clear, till now. MIght come the day in the future that he might throw some shyte, more when he is entering his final stages, we dunno.
