The Reds’ 44-goal top scorer was forced off midway through the first half of Saturday’s Champions League final defeat to Real Madrid with a shoulder injury he sustained in a tangle with Ramos.
Ramos appeared to cling on to the Egypt international as they fell to the ground, leaving Egyptian fans incensed.
Ramos is an active Twitter user, posting on the @sergioramos account which has since been sent thousands of angry messages.
“Die for the Egyptian people,” wrote one while another said: “You injured Mohammed Salah’s shoulder, and you did it on purpose. You’re a coward and you die like a coward.”
“Go to hell Ramos!! U will die after hurting m salah,” added a fellow fan.
Another wrote: “The whole Egyptian people are looking for you, if they find you, you will die….”
Ramos has not replied to any of the messages directly but he did take to Twitter on Monday to post a heartfelt message to girlfriend Pilar Rubio.
The defender wrote: “You are the force that drives my life. You make my life happy. I dedicate every success to you, because that success is yours. @PilarRubio_”
Salah, meanwhile, will travel to Spain on Wednesday to undergo treatment on his shoulder injury, the Egyptian Football Federation have announced.
Salah tweeted on Sunday that he remained “confident” of being available for Egypt’s World Cup campaign in Russia, and on Monday evening it was confirmed he will head to Spain.
The Egyptian federation said Salah began his rehabilitation programme on Sunday, and was in “high spirits” and “determined to return quickly to the ranks of the team”.
He will receive treatment in Spain, accompanied by the president of the Egyptian federation, the national team doctor and Liverpool medics.
“Mohamed Salah began his treatment programme on Sunday, when he confirmed in a telephone conversation with the technical and administrative staff of the team he was in high spirits and determined to return quickly to the ranks of the team,” the federation said in a statement on its website.
Liverpool manager Jurgen Klopp feared the issue could rule Salah out of the World Cup, which starts in just under three weeks, but the player posted a positive message on Twitter on Sunday.
“It was a very tough night, but I’m a fighter. Despite the odds, I’m confident that I’ll be in Russia to make you all proud,” the 25-year-old wrote.
“Your love and support will give me the strength I need.”
