Some of those other cult-heroes cost nothing. They were grafters but generally poor.
This guy cost us £13m so I think people shouldn't be so quick to judge him as sub-standard, like Koeman did.
Martinez may have faults in terms of his football style, but I'm sure he's not totally incompetent at judging a player that we were looking at signing.
Did he not take the 'gamble' on Lukaku for £28m when many fans thought that was way too much and preferred to talk about his faults ?
