Rafa remains the biggest indicator as to what's going on with the take over, I think.
I have a feeling that if it was completely dead in the water, and PCP had walked away, he would have come out fighting against Ashley. However, as he is continuing to play everything with a straight bat, and isn't being antagonistic towards Ashley, then it suggests to me that something might still be possible, however small.
The moment his attitude turns though, then we know it's all over. Every press conference, i'm waiting for his "It is a fact..." moment.
