Liverpool maintained their top position on the Premier League table with a comfortable 3-1 win over Arsenal aided by two strikes from Egyptian international, Mo Salah.
Liverpool took control when Matip put them ahead with a powerful header from Trent Alexander-Arnold’s corner four minutes before the interval.
And any hopes manager Unai Emery had of watching his side mount a recovery were snuffed out in the 49th minute after a moment of madness from new signing David Luiz, who needlessly dragged Salah back in the area.
Liverpool’s Egyptian attacker drilled home the penalty and then embarrassed Luiz again out on the touchline at the start of a dazzling run that ended with a low, curling finish into the bottom corner just before the hour.
Arsenal substitute Lucas Torreira pulled one back late on, but nothing was getting in the way of Liverpool’s 12th successive league victory, equalling their best sequence in the top flight under Kenny Dalglish between April and October 1990.
