#3 Style of play
Even though all of football is hysterical in their praise of Klopp, Pochettino and Guardiola for their effervescent and proactive pressing game, it is quite debatable whether such a demanding regime is sustainable over the course of four competitions through a season.
Towards the rear end of last season, Klopp regularly fielded youngsters in Premier League outings as they strolled through the Europa League – leading to such results as the 3-1 loss at Swansea. Conversely, Pochettino tried to boost his title chase by sacrificing the Europa League – exiting meekly at the hands of Borussia without so much as a hint of a fight.
Early season, Premier League running statistics revealed Manchester United covered the least amount of distance in the Premier League whereas Liverpool ran the most. Coupled with the results the two experienced at the time, the stat was used to mock Mourinho's outdated gameplay. The course of events since the turn of the year forces a rethink – perhaps United has peaked at the right time thanks in part to their manager's measured approach.
