Pumped his own money in
Backed every manager we have had
Got us one of the most decorated managers in football
On the verge of getting us a world class stadium on the river front
How anyone can look at that at this point and say he's been anything but fantastic for us needs their heads testing!
Yes you can point to the BFS appointment or the couple of managerial/DoF appointments but people forget how new he was to this, at Arsenal, there was only ever Wenger while he was there. Whatever mistakes he did make, he learned and moved on.
For me the only major gaffe that should truly have been avoided was appointing a scout as a DOF.
Managerial appointments are always a gamble and while people may not agree with them it's usually a matter of opinion. He's shown that in those circumstances he's willing to realise things aren't working and change them even if it is financially costly and an admission of getting it wrong.
