The Egyptian faces a race against time to be fit for the World Cup after sustaining a shoulder injury in Liverpool’s 3-1 Champions League final defeat to Real Madrid.
The Pharaoh has had a fabulous first season at Anfield, scoring 44 goals since his £34m move from Roma.
And Salah says he improved at Stamford Bridge, learning “a lot” from Mourinho and Frank Lampard.
“I learned a lot from Jose, from the club,” Salah told ex-teammate Lampard on BT Sport prior to the Champions League final.
“We would meet each other in Chelsea, and with you[Lampard], you always used to train alone after the training and I saw you do that, I would always come to you and try to improve, and I learned a lot.”
