Philippe Coutinho (Liverpool)
The little Brazilian had been a shadow of himself under Brendan Rodgers earlier this season - but with the arrival of Jurgen Klopp he has been rejuvenated with two goals in the win at Chelsea and a masterly display here. When he plays well, Liverpool play well.
Roberto Firmino (Liverpool)
The £29m signing from Hoffenheim made a slow start but Klopp was an admirer from the Bundesliga and clearly regards him as an important player, using him in an advanced role in preference to Christian Benteke in the away games at Chelsea and here, where he showed his class again.
Emre Can (Liverpool)
Another player feeling the benefit of Jurgen Klopp's arrival. The Germany international was shifted all over the place by Brendan Rodgers, including right-back and part of a three-man central defence. Klopp has put him in his familiar midfield role and he helped to create Firmino's brilliant third.
Eliaquim Mangala (Man City
Certainly not blaming this player for Manchester City's shocking defensive display but his early own goal increased the nerves and uncertainty, underlining just how much they missed captain Vincent Kompany.
