Although Redknapp feels that British managers do not get the same opportunities with what he calls the “great teams”, he has no doubts about the pedigree of Mourinho and believes the self-styled ‘Special One’ could go down as the greatest manager in history. “He’s proved that he’s a fantastic manager wherever he has been,” Redknapp said. “He’s going to be in the game for many years to come and he could end up as the greatest manager of all time [but] he is not going to walk into a team in the bottom four or five at the moment and turn them into a top-six team. That’s not going to happen, as clever as he might be – and he is very clever.
