Liverpool thrust themselves firmly back into the battle for a place in the Premier League's top four as they outclassed abject Arsenal at Emirates Stadium.
Chelsea's shock thrashing at home to West Brom earlier in the day opened the door for Liverpool - and Jurgen Klopp's men burst straight through it in style with a victory that leaves them in fifth, only two points behind Thomas Tuchel's side.
The only surprise was that it took dominant Liverpool so long to make their superiority count.
They finally got the breakthrough they deserved after 64 minutes when Diogo Jota headed Trent Alexander-Arnold's brilliant delivery past Arsenal goalkeeper Bernd Leno moments after he replaced Andy Robertson.
It was not only the decisive moment of the contest but also a timely reminder of the quality Alexander-Arnold possesses at a time when England manager Gareth Southgate feels he can do without him.
