The northern side achieved their victory in London Stadium thanks to Mohamed Salah and Giorginio Wijnaldum collectively scoring three goals.
Just before the first goal by Mohamed Salah, Jurgen Klopp replaced James Milner with Curtis Jones.
Soon, Curtis played a crucial role in aiding Salah to score one more goal. Moments after the second goal, Klopp turned to Milner and gave his footballer one of famous bear hugs.
Reds fans really enjoyed Kloop’s reaction.
Finally, in the 87th minute, West Ham's Craig Dawson scored a goal in extra time.
Liverpool have 40 points and are in third in the Premier League and West Ham have 35 points and are fifth.
