From my perspective, Ajay's posts have been extremely well written and appear (as much as I know) close to the action. We'll know in time how close to the action Ajay's source is but at this point in time, I would say very close.
As for HappyBlue, I don't know the fella and don't read BlueVibe so I can't comment on him, his postings or sources. As for saying who's better than who, I'd say that's a waste of time...a bit like my dad's bigger than your dad playground crap I last heard about thirty years ago.
I make a habit in my life not to trust anybody until I get to know them. Trusting someone you don't know from a football forum is difficult to say the least but what I will say is that Ajay is a regular, consistent and as mentioned well written poster; based on his postings so far and the information currently in the public domain I think Ajay is one of the few on here that can be trusted.
