The 30-year-old Algerian winger scored at the Parc des Princes in the first-leg semi-final Champions League clash to ensure City's 2-1 comeback victory last month.
And Mahrez delivered another impactful performance on Tuesday as his brace in the second-leg clash at the Etihad fired City into the Champions League final.
Mahrez, who was signed from Leicester City in 2018, has made 45 appearances across all competitions this season and scored 14 times and registered seven assists.
The City winger's superb showing against PSG in both matches has been hailed by Adrian Durham, who insisted Mahrez is "right up there" with the world-class stars in football right now.
Speaking on talkSPORT, Durham said: "Mahrez made an impact in both semi-finals.
"He's arguably -- and he's about to win his third title -- the best player in the world right now.
"Even if he's not the very best, he's right up there."
Mahrez could add even more silverware to his trophy cabinet after City captured the League Cup last month.
City are inching closer to securing the Premier League title this season before they turn their attention to the Champions League final in May against Chelsea.
Durham's bold statement on Mahrez was dismissed by fellow talkSPORT co-host Darren Gough, who claimed three other City players were better than the Algeria captain.
"His form is fantastic but I'd be a little bit calmer in my appraisal in that position," he said.
"In his position, you could argue he's the best in that position, but is he one of the best now? I find that hard to suggest.
"At Man City right now, [Phil] Foden, [Kevin] De Bruyne and [Ruben] Dias are better."
