LONDON — Liverpool roared back from a goal down to beat Arsenal 4-3 in a thrilling start to its Premier League season on Sunday.

Theo Walcott put Arsenal ahead in the 31st, less than two minutes after missing a penalty, only for Philippe Coutinho to equalize for Liverpool in first-half stoppage time with a spectacular free kick.

It proved to be a turning point as Liverpool tore Arsenal's makeshift defence to shreds after the interval, with superb goals by Adam Lallana, Coutinho and Sadio Mane giving the visitors a 4-1 lead by the 63rd minute.

A solo goal by substitute Alex Oxlade-Chamberlain and a glancing header by defender Calum Chambers in the 75th hauled Arsenal back into the game, but there was no equalizer in a frantic finale at Emirates Stadium.
