As you can see in the footage below, the travelling Kop loved the celebration from the Reds boss.
If you keep an eye on Liverpool goalkeeper Alisson, you can see him mimicking Klopp's fist-pumps. The Brazilian was clearly a fan of the German's post-match celebration.
On another note, Alisson was solid against Manchester United. The 29-year-old registered a WhoScored player rating of 7.43 against the Red Devils.
