Salah joined Chelsea from FC Basel in January 2014 but the Egypt international failed to win regular game time at Stamford Bridge.

He was sent to Fiorentina a year later on loan before heading to Roma on a season-long deal that included a permanent clause.

Roma triggered the option at the end of the campaign - six months after Chelsea had sacked Mourinho.

Salah has since returned to the Premier League with Liverpool and taken English football by storm, scoring 43 goals in 47 games.

Mourinho has been left with egg on his face over Salah’s sensational form but the Manchester United boss is delighted for his former player.

Speaking at a press conference, Mourinho said: “It’s easier for you to say negative things about me and not positive things. Everybody knows I bought Salah.
