The Reds routed Arsenal 4-0 over the weekend with Sadio Mane, Roberto Firmino, Mohamed Salah and Daniel Sturridge all contributing a goal.
"For me, they are the best, they caused Arsenal a lot of problems," Lovren stated with reference to the starting trio of Mane, Firmino and Salah.
"It's a long season and we will see towards the end of the season who is in the first place, but you can see the difference those three players make.
"I'm lucky that I don't have to face them very often in training. It tends to be the guys who aren't in the first-eleven.
"All three of them are top players, they have pace and great quality. They are amazing. It would be quite difficult for any defender when you are up against Salah, Mane and Firmino."
After three rounds of Premier League action the trio share seven goals between them.
