Jurgen Klopp believes Sadio Mane's new contract is evidence of the progress Liverpool have made in recent years, with their star men now able to "make the next step" at Anfield.
Mane committed to a two-year extension on Thursday, keeping him on Merseyside until 2023, as Liverpool look to mount a title challenge this season.
The likes of Fernando Torres, Luis Suarez and Philippe Coutinho have moved on in search of silverware in the past, but Klopp is now confident he has a team that can contend.
"I'm really pleased [Mane] signed the contract," said the Reds boss. "It's a big signing, a player in a big moment in his career.
"To extend the contract is more than the signing, it's a statement and I'm happy about that. It really shows a bit of the change the club did in the last few years.
"A few years ago it constantly happened, where players in a good moment thought they had to leave to make the next step. Now our boys think they can make the next step here."
And Klopp was pleased to be able to show his faith in a player who has delivered consistently for Liverpool over recent seasons.
“That’s a part of the business, you sign a player and you hope it will work out, then after one year people come up because of interest from other clubs," he added.
"This club shows always that we realise the value of players with new contracts.
“We are comfortable with the squad, but it’s now important that we use that quality. Signing a new contract is only five seconds. It’s only one thing, and now we have to carry on. I’ve never shown any doubt about the quality of the squad.
“It’s good that it’s settled and nobody needs to come and ask for these players at least. That’s it.”
