Liverpool continued their unbeaten start to the season with an impressive 4-0 victory over Leicester City in Matchweek 19.
Heaton was in inspired form, making numerous saves to earn a clean sheet against a Norwich City team who dominated at Villa Park.
Alexander-Arnold has emerged as one of the best playmakers in the league and the right-back was sensational against Leicester, with a great goal and two assists. The Liverpool academy graduate just keeps getting better.
Van Dijk kept Jamie Vardy quiet throughout the match. The Premier League's top scorer barely had a sniff, with the towering Dutchman in his finest form.
As if keeping Alexander-Arnold at bay on one side wasn't tough enough, Liverpool's left-back put in another excellent display as the Premier League leaders kept a third clean sheet in a row.
Armstrong produced a moment of brilliance to set up Nathan Redmond's goal and was a creative presence in attacking midfield. His best performance in a Southampton shirt.
Grealish continued his stellar form this season with a skilful assist for match-winner Conor Hourihane. He is the star in this Villa team and is surely making a case to be in Gareth Southgate's England squad.
Firmino's touch and finish for his second goal at King Power Stadium was out of this world. He led the line magnificently and deserved his two goals for the Premier League leaders.
Martial scored twice and was unlucky not to get a hat-trick, having hit the inside of the post. It was an impressive display from the Frenchman and his understanding with Marcus Rashford and Mason Greenwood is exciting for Man Utd fans.
Manager: Jurgen Klopp (LIV)
Klopp masterminded an outstanding performance by a Liverpool team who will be very difficult to stop this season. You wouldn't have thought it was second against first given the way the Reds won so commandingly.
