This ability to drop players into the side and watch them thrive – or at the very least make game-altering contributions – is something few of Liverpool’s Premier League rivals can do with confidence.
Mikel Arteta has found that at Arsenal, which perhaps explains why he is hesitant to rotate underperforming players such as Willian and Hector Bellerin.
And at Manchester United, while Ole Gunnar Solskjaer has a strong starting XI, there is a drop off in quality behind that, especially in the final third.
Liverpool’s win at Palace has opened, temporarily at least, a six-point gap at the top of the table.
And given their performance at Selhurst Park, the fact none of Mane, Salah, or Firmino played 90 minutes, and that Thiago is close to a return, the biggest concern for the Reds’ rivals should be Klopp’s side may only get stronger in the weeks to come.
