Oh dear god that's stupid.
"riding high on the back of happening to be at Barca at the right time"
He's the person who made it the right time to be at Barcelona. He's the person who stood in front of the Barcelona board and told them not to hire the experienced, hottest manager on the market, Jose Mourinho, but instead hire the B team coach with no experience of senior management to take over in a time of crisis.
Whatever you think of his work at City, the idea he lucked into a Barca job at the right time is laughably stupid.
