Mohamed Salah has scored a goal in 27 of his opening 50 appearances in the Premier League; only Andrew Cole (31 games) scored in more of his first 50 apps in the competition, while Alan Shearer also scored in 27.
Liverpool are only the second side in Premier League history to score 4+ goals in four consecutive games against a single opponent, after Tottenham v Stoke.
Sadio Mane has been directly involved in six goals in his last four Premier League appearances against West Ham (3 goals, 3 assists).
Sadio Mané is the first Liverpool player to score in three consecutive opening top-flight fixtures since John Barnes between 1989-90 and 1991-92.
