Premier League 2018-19: 3 takeaways from Liverpool's 3-1 win against Manchester United

#2 Masterclass substitution from Jurgen Klopp

Xherdan Shaqiri scored a brace against Manchester United

Liverpool had a menace and desire about them from the first whistle of the game. United were pegged back in the face of the relentless pressure from the home side. Which is why 1-1 at half-time seemed like an unfair scoreline for the fans; the home side had largely dominated the opening 45 minutes of the game, with nothing to show for it.

As the second half commenced, something needed to be changed to break United's rearguard. After the first quarter of the second half, Klopp introduced Shaqiri into the frame, replacing Keita to bring in a more attacking flavor into the game.

The Swiss international didn't disappoint as he gave the home side the lead with a deflected shot into the top corner.

Shaqiri scored his second immediately after with another deflected shot, this time off Eric Bailly.

It was a substitution that paid rich dividends for Klopp, and a move that the Swiss will remember for a long time.
