The 29-year-old sees his current contract at Anfield reach its conclusion at the end of next season, with the Reds in talks with the Egypt international over extending his stay on Merseyside.
However, reports have suggested that a breakthrough in negotiations are still some distance away, leading to mass speculation over his future.
Salah has been in sensational form this season, with the Liverpool star scoring 17 goals in as many games in all competitions so far this term – helping the Reds fight Chelsea at the top of the Premier League table and on the European front.
Drogba, when speaking about Salah to Al-Axis TV, via the Liverpool Echo, said: “If I am selfish, I will tell Salah to leave Liverpool and return to Chelsea.
“My opinion is that Salah will remain the best, no matter if he continues at Liverpool or if he moves. Any other team would perform better (with Salah) because he understands what he is doing, is good at scoring and creating goals and only needs the confidence of the coach.
“I do not know what his decision would be. This is his decision alone and his future. Wherever he goes, I will be one of his fans.”
Salah’s future at Anfield is uncertain, but the man himself revealed that he would like to stay at Liverpool for the remainder of his career, when being interviewed by Sky Sports towards the end of October.
“It does not depend with me. If you ask me, I would love to stay until the last day of my football (career), but I can’t say much, it’s not in my hands,” Salah explained last month.
“It depends on what the club wants, not what depends with me. At the moment, I can’t see myself ever playing against Liverpool, that would make me sad.
“It’s hard, I don’t want to talk about it. It would make me really sad, at the moment, I don’t see myself against Liverpool but let’s see what happens in the future.”
Salah represented Chelsea for two years between 2014 and 2016 after signing from Basel. In his time at Stamford Bridge, he made just 13 Premier League appearances, with the majority of his time spent out on loan at Fiorentina and then Roma.
