Salah and Mane, along with fellow attacker Roberto Firmino and midfielder Naby Keita, have contracts that expire next year. With Klopp now staying until 2026, there is a greater degree of security at the club, but the German is not convinced that will make a huge difference to individual players' decisions.
"If it is a positive sign for the boys, great, but I don't think this will be the one decisive thing for whatever decision they want to make," he said. "It is their own life but we just wanted to guarantee that everyone who wants to be here knows what he can expect."
Egypt international Salah, whose negotiations have dragged on for several months, admitted last week it was not certain he would remain at Anfield. But Klopp said he did not make judgements about players' loyalty based on whether they wanted to go elsewhere.
