The Reds lost the Brazilian playmaker to Barcelona during the January transfer window in a deal worth a reported £146m, which they have since spent on a number of new recruits.
Klopp insists that, despite Liverpool missing out on the signing of attacking midfielder Nabil Fekir, Liverpool were never looking to directly replace Coutinho.
"You cannot replace Phil Coutinho with exactly the same kind of player," he told reporters. "He's Phil Coutinho. He has a specific style of play, tactically an outstanding player, can play as the winger, the '10', the '8' - really great. I don't want to put one of my players in the position where people will now say constantly 'he's the Phil replacement'.
"I think the biggest thing we did in the second half of last season was that we didn't need to speak too much about Phil. That wasn't clear in January. How could we have known that? If we had still had Phil then we could have played with Phil in the final.
"Mo [Salah] goes out [injured], but Phil still there. Phil on the left wing, bring Sadio [Mane] to the other side, bring midfielder on – it's a different story. It would have been nice but he wasn't here any more. We wish him well.
"We don't need to replace Phil. We need to make a squad for the next year. Out there on the market, there isn't a Phil Coutinho lite. It's not there. But there are a lot of good players and we have brought a few of them in."
Coutinho scored eight goals and chipped in with a further five assists during the second half of last season's La Liga campaign.
