Lallana explains Klopp told the side to go for the jugular against Chelsea.
Lallana said: "The manager’s message at half-time was - it’s there for us, the points are there for the taking.
“He said not to think about Chelsea’s situation and just to worry about us. It was all about us taking the next step forward.
“We wanted us to be positive and aggressive and we did that. We took control in the second half and deserved the points.“
Second half strikes from Philippe Coutinho and Christian Benteke ultimately made the difference as the Reds recorded their first league win since Klopp's arrival - moving them to within four points of the Champions League places in the process.
It also heaped the misery on defending champions Chelsea, whose bad run to the season continued as they currently sit in 15th place, six points behind Liverpool.
For Liverpool, however, it saw a return to form for Philippe Coutinho, and emphasises how important Christian Benteke can be for the side this season, as his introduction on the hour mark caused the Chelsea back line problem with the Belgian heavily involved in Coutinho's second goal as well as wrapping the game up.L
Lallana added: “Christian’s contribution was also massive. He had a great impact from the bench. He came on and gave us a completely different dimension.
“We’re going to need the whole squad this season if we’re going to do well in each competition and they are two big players for us.”
The Reds will look to maintain some of this momentum when they go into their crucial Europa League match with Rubin Kazan on Thursday, knowing a win would put them in pole position to qualify for the knock-out stages.
It seems that Klopp's words can work as an inspiration for his side, and there will probably be more team talks of that ilk to come, along with big performances from certain players. Both may be needed if the Reds are going to see some tangible success this season.
