The likelihood is that football agents have played a big role as the go betweens and this is the real reason for the different versions of events and both sides feeling aggrieved.
It is likely that it is Pere Guardiola is the man who holds the key to the whole messy dispute and knows who knew what when and is the man who needs to answer questions posed by both sides.
The same could be said of Mark Mackay and Diafra Sakho, prior to the Sakho deadline day pantomime, rumours came out of France from reliable sources that Sakho was been offered to Ligue 1 clubs. The question is who was offering him around to the clubs and who authorised him to do so? What role did the son of Willie MacKay have in the Sakho affair?
