Click to reveal a possible Liverpool line-up next season with Philippe Coutinho
Klopp is hopeful of another positive season following their fourth-placed finish last term.
"When we finished last season in fourth position everybody was really happy about it - it was really a good result for a big effort,” he said.
"We knew also there would be a qualification game, and now it is coming up. But the first challenge we have to face is playing Watford, even though everybody is thinking about the Champions League qualifiers. So Watford is the first target.
"We are in a good shape. The players are in a good mood, the attitude in all the training sessions was really good."
Watford, under new boss Marco Silva, have added well this summer and are eyeing progress.
"Our main goal is to continue to stay in the Premier League, but we want to do better than the last two seasons,” Silva said.
"That's important as well to us, and the way I work is to think game-by-game, prepare week-by-week, and be strong on matchdays."
