Quite right!
Hughes lost himself the job as he had no tactical awareness.
I was a Hughes 'inner' until Tottenham. He starts the match with no wide right player, so 'Arry puts 2 men on Robbeh who is thus stifled so effectively, he is replaced by Petrov, who is still faced with 2 defenders as we still have no wide right outlet.
'Arry plays Crouch in front of Defoe so his flick ons can be contested by Defoe. Ade is left on his own and if he does get a flick on, it can only go to a Spurs player as there is no city player behind him. What is the incentive for Ade to contest high balls to him?
Les then brings on Santa Cruz, who like Ade is great in the air, but we still have no wide right player and Petrov has 2 on him all the time, so, apart from corners, we don't put a single cross in for Ade and Santa to have a go at.
It's not rocket science, but Hughes and his crew never seemed to cotton on and go to plan B.
That is why Les lost the job
