Dude be for fucking real. Its 8th September, window closes for main leagues 9 days ago, we have no negotiation wiggle room here. Its either we play him full salary to sit in the stands, or they take him loan with option and pay his full salary. There is no negotiating skill involved in this, this is a last resort deal to move a player before he is forced to stay with us and we pay him to roll his thumbs.
And no its not established fact Mourinho been after him all summer, if that was true would be tangible permanent transfer offers. But just like its the case with Kostic who sees them as last resort, they most likely view him the same. Otherwise they wouldnt loan him in 8th September.
