Adam Lallana believes Liverpool's thrilling 4-3 win over Arsenal has laid down a benchmark for their season -- but admits there is still plenty of room for improvement.
Liverpool fought back from 1-0 down to take a 4-1 lead at the Emirates before the Gunners pulled back to within a goal of Jurgen Klopp's side. Rather than toast the win, though, Lallana says there is lots to work on before the next game.
"At 4-1 we maybe got a bit complacent, a bit over the top," he told Liverpool's official website.
"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, for sure. He won't be entirely happy with the performance -- there will definitely be things we need to work on. We've got a full week's training now to prepare for Burnley."
Lallana praised Coutinho's stunning equaliser, a free-kick that Petr Cech could not get close to, and the England international does not think anyone else will be on free-kick duty for Liverpool any time soon.
"A great bit of magic from Phil gave us that belief and confidence going into half-time," he said. "That was massive for us and we came out in the second half like we were possessed, it was brilliant.
"Phil again came up trumps with the free-kick. We were working on them a couple of days ago -- there's just no chance anyone is getting anywhere near a free-kick.
"But we all want him to have them because he can produce that, and I think that's the best I've ever seen him score. It was further out than usual and it was right in the top corner, the keeper had no chance."
