Liverpool head into a weekend when they host Arsenal at Anfield six points clear at the top of the Premier League and seeking to extend their unbeaten record in the division so far this season to 20 matches.
Having qualified from a group also including Paris Saint-Germain, Napoli and Red Star Belgrade, the Reds have a last-16 tie with Bayern Munich on the horizon in the Champions League and face Wolverhampton Wanderers in the third round of the FA Cup next month.
And Lovren feels Klopp’s work in the transfer market means Liverpool are primed to achieve success this term.
“There are a lot of players still here and it was like a puzzle, you just keep bringing in these players you need and now it’s a perfect match,” the centre-back said.
“You feel that in the squad, it’s how it should be. There has always been something missing all these years but now we have everything.”
Go behind the scenes of LFC 4-0 NUFC
Croatia international Lovren set the Reds on their way to a convincing 4-0 win over Newcastle United on Boxing Day with a perfectly-struck half-volley.
That victory, coupled with results elsewhere, extended Klopp’s side’s advantage over their closest challengers at the top of the table, but Lovren insists he and his teammates are focused solely on themselves.
“It’s only about us and that’s how we should do it always. We learn from these previous seasons,” the No.6 explained.
“There’s no pressure. In the previous years, yes, but now when you look in the dressing room, when you go into Melwood in the morning, everybody is happy, nobody talks about anything other than the next game.
“We can’t talk about something that will happen in five or six months. We go game by game and we will see where we finish. For us, every game is a final. It’s good to hear all these positive words but we don’t live on these positive words, we live on winning games.”
