In football terms, Sam Allardyce reckons nobody knows the game better – not Pep Guardiola, not Jurgen Klopp, not Mikel Arteta.
That's quite a claim. But if Big Sam saves Leeds United from relegation, he'll become an instant messiah in Yorkshire. And nobody is better-suited to dig them out of their predicament. Not Pep, not Klopp, nor Arteta.
Although his last rescue act at West Brom fell short – he won only four of his 26 games in charge and suffered the first relegation of his managerial career – I have worked with Big Sam in the past and can vouch for his attention to detail.
