The Reds will seal a place in the Champions League qualifiers for 2017-18 if they pick up three points against an already-relegated Boro side.
And Klopp is eager for supporters to arrive at Anfield for one last time this season with complete faith their team will finish the job.
Asked what his message for fans ahead of the game is, the manager told Liverpoolfc.com: “Nothing special, actually. When I started here I said we had to change from doubters to believers and I think now we have a few days before the game, so look forward to it, be positive.
“If somebody comes to you and says ‘but if…’ – and that’s not the most used words in and around Liverpool – but if, then send him out, say ‘come on, go away, I don’t want to hear about it’.
“There’s no reason for it. This team has shown so much this season and we will be ready for this game, and we should really be positive and try to enjoy the game. Maybe it’s nervy for the supporters around, but it’s the job to do, unfortunately.
“I’m really looking forward to it and I could use this moment then to say ‘thank you’ for the outstanding atmospheres this season. I don’t want to say ‘you can’t do better’, but it was already pretty good this season and we’ve enjoyed it a lot. Let’s go one more time and get the full package.”
