Liverpool still have work to do, says Adam Lallana
Adam Lallana believes Liverpool's thrilling win over Arsenal has laid down a benchmark - but admits there is still plenty of room for improvement.
The Reds were 4-3 victors at the Emirates 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 Philippe Coutinho free-kick.
The visitors ran rampant after the interval as Lallana put them in front, Coutinho added a third and new-boy Sadio Mane thrashed home a fourth.
Arsenal responded and hit back through substitute Alex Oxlade-Chamberlain and Calum Chambers but Liverpool held on to take three points - with Lallana aware that it was not a perfect afternoon for Jurgen Klopp's side.
"At 4-1 we maybe got a bit complacent," the England international said. "We were soon back down to earth when it was 4-3. I was on the bench in the last 10 minutes and it was unbearable to watch at times. But we have a benchmark now and we can assess it and look at things we need to improve on.
"The manager will do that, he won't be entirely happy with the performance. We've got a full week now to prepare for Burnley."
Lallana praised Coutinho's stunning equaliser and does not think anyone else will be on free-kick duty any time soon.
"Phil again came up trumps. There's just no chance anyone is getting anywhere near a free-kick," he said. "But we all want him to have them because he can produce that, that's the best I've ever seen him score."
