I totally agree with this, but you realize this undercuts Klopp's entire stance, right?
Like if we took Klopp's arguments at face value, wouldn't he have taken players off because that would have been the move that benefits him in the long run? He's contended that the schedule/minutes players are playing are putting them at risk and five subs would address that, so taking that to its logical end and with the holiday period coming up, if he really believed was he's shouted at every press conference making subs would have been the smart play regardless of how the game's going. Mind you, we're talking about a game yesterday that was a 1-1 draw with 80% of the ball at the 60-minute mark or whatever.
People might not like hearing this, but I think Klopp and Mourinho are more alike than most would like to admit. He's made this substitution boogeyman as a deflecting tool that he can yell about rather than his players or performance. Mourinho is just more caustic and douchey about it.
