Players try harder when a new manager arrives at a club. Gary Neville presented the stats which proved it on yesterday evening's edition of Monday Night Football.
With the exception of Dick Advocaat, running stats shot through the roof for the first game of all recently appointed managers. The table only included those managers who were appointed in mid-season.
No manager has made a bigger impact in this regard than Jurgen Klopp.
Liverpool players performed a total of 614 sprints at White Hart Lane on Saturday, a statistic which Neville characterises as 'off the scale'.
Half of the Liverpool starting line-up covered more distance than they ever had before in that game. Carragher said the increase in workrate was such that it was as if Liverpool had another man on the pitch.
But Neville isn't sure whether Klopp's high pressing, hard running game is sustainable, given the energy sapping nature of English football.
