Liverpool midfielder Adam Lallana has told his teammates they must be more disciplined as a unit if they want to be successful this season, speaking to BBC Sport.
It was a scintillating display of attacking football from them as they threatened to score more than the four goals that they managed.

At the other end they were less than impressive though as they let the Gunners back into the game to set up a nervous finish.
And reacting to the result, Lallana has told his teammates they must improve their discipline as a unit if they are to be successful.
“It was a very entertaining game, we didn’t start so brightly but it’s always difficult coming to Arsenal,” he told BBC Sport.
“We got a bit complacent at 4-1, but Arsenal are a top team. If we want to achieve something special this year we have to be more disciplined as a unit.”

The defensive showing from his side will certainly have left Klopp concerned despite the positive result.
Chief among his worries will be left back Alberto Moreno, who once again failed to impress for the Reds.
It is the latest poor display from the Spaniard and Klopp must surely be determined to find a new left back before the end of the transfer window as a result.
