Liverpool laid down a marker, says Adam Lallana

Adam Lallana believes Liverpool’s thrilling win over Arsenal has laid down a benchmark for their season, but admits there is still plenty of room for improvement.

The Reds were 4-3 victors at the Emirates Stadium to get their Premier League campaign off to a winning start, with their four goals coming in a devastating 18-minute spell.

Theo Walcott gave Arsenal the lead just 69 seconds after seeing a penalty saved by Simon Mignolet, with Liverpool drawing level on the stroke of half-time courtesy of a sublime Philippe Coutinho free-kick.
