The club's progress has led to top players, including Salah and Firmino, signing new long-term contracts earlier this year and Klopp is optimistic that Mane will follow suit. "We are Liverpool as a team and the boys want to be part of it", Klopp told British media.
Alisson joined the Reds from the Italian side for a world record fee and already looks sharp in training.
It is an improved situation that these players don't use us and then go.
Liverpool are now training in south-eastern France ahead of their final pre-season friendlies and are expected to return to Melwood next week before the opening day of the Premier League.
Alisson will get his first taste of Premier League action against revamped West Ham.
Ahead of that, the Reds have travelled out to France to continue their preparations for the 2018-19 campaign at a picturesque sporting complex in Evian-les-Baines.
"It's also showed me that the team are very well adapted to it and everyone seems to be physically fit, not to say technically - they're all great players after all".
"I've also already worked with "Mo Mo" (Salah), the three of them will be very important for me to settle into the squad".
"We'll play two friendlies before this game and I'm sure the hard work the squad have put in so far is going to help me become a member of the squad as quickly as possible so that I am 100 percent ready for our first game to kick off the Premier League in a good way".
Klopp added: "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".
