The depth of the team would have always been necessary if Liverpool had put together a significant title challenge this season.
And so he has already shown.
Jurgen Klopp mixed his pack for the trip to Burnley and despite having gone 1-0 down in the night, Liverpool came back to win and keep the title challenge going.
The Reds boss played his part in the victory not only by choosing the right team to do the job, but also by changing the course of the game with his substitutes.
Roberto Firmino and Mohamed Salah arrived to change the result of the match. The Brazilian put Liverpool ahead after James Milner equalized, before Salah built Xherdan Shaqiri to score the third goal of the match.
They are not the only substitutes making a significant impact this week, of course. Divock Origi appeared from the bench to become the unlikely derby hero with a last-ditch attack against Everton.
It was a theme throughout the season so far, with Daniel Sturridge appearing on the bench to score against West Ham and Chelsea, Shaqiri scoring a late goal against Cardiff and Firmino getting the winner against Paris-Saint Germain in the Champions League.
In total, substitute goals equaled seven extra points in the Premier League and three in the Champions League, underscoring the impact that Klopp had on the sidelines this season.
In fact, six sub goals are already higher than the Liverpool total managed throughout last season.
It is another clear sign of the progress Liverpool has made this season with Klopp, whose summer purchases have not only significantly improved the defense, but have also given the Reds a team capable of competing on all fronts. .
