#2 Sergio Aguero vs Joel Matip
Sergio Aguero may or may not start against Liverpool but his record against the Merseyside club speaks for itself. The Argentine has scored 5 goals in his last 5 home matches against Liverpool in the Premier League.
Thus, either as a starter or as a sub, Aguero has a great chance to hurt Liverpool and the Reds defence will have their task cut out. The primary responsibility of stopping the PL's most effective striker will rest with Joel Matip, Liverpool's no.1 centre-back.
The former Schalke man is good at reading the game and will have to be at his best to detect and prevent the clever runs of Aguero. The outcome of this matchup will have a major say on who wins the match and is one to watch out for.
