Jose might be a class A w***er but he's done well shipping out 2 players he clearly deemed not good enough already.
Depay 16m - rising to 21m. They paid 25m with potential to rise 31m (not met obv)
Morgan 22m. They paid 24/25m iirc.
Took gambles, didn't work out (although I think Morgan especially will be good) and lost a max of 18m...what a big shame. Point is, he's come in and making his mark, being ruthless and not holding on to players who shouldn't be there, I find this a major flaw in Arsene.
