I'd love to know the full story here, apparently Porto behaved like [Poor language removed], agree a fee, then rejecting it and wanting more, Brahimi is livid they stopped him from moving, he was sold on the idea and wanted to try the Premiership.
It's ok saying it's amateur hour on our part, but Porto have history for doing stuff like this, especially when the player has more than one party owning them.
There comes a time when you just have to refuse them upping the asking price and tell them to feck off.
