Jurgen Klopp side Liverpool secured a basic advantage over Arsenal in the battle for a place in the English Premier League's top four with a well - deserved victory at Anfield.
The Gunners coach Arsene Wenger gambled by leaving Alexis Sanchez - his leading scorer with 17 Premier League goal - on the bench but the trick failed poorly as Liverpool took control by the half - time.
Liverpool's striker Roberto Firmino's far - post finish put the Reds side ahead after nine - minutes and midfielder Sadio Mane confirmed their superiority with an powerful strike before half - time.
The Chilean striker ( Sanchez ), predictably appeared as a substitute at the start of the second half and set up a goal for striker Danny Welback that gave the Gunners hope but midfielder Georginio Wijnaldum hit on the break deep into injury time to seal Liverpool's victory.
Jurgen Klopp side are now up to the third level with Manchester City on 52 points although the Arsene Wenger are now in fifth trailing that pair by two points.
The Gunners and Arsene Wenger had so much floating on this match - a meeting where they knew defeat would leave them outside the Premier League's top four.
