It is Krishna's second selection in a FIFA Team of the Week this season after first making the cut in late January.
The 31-year-old Fijian earned his second citation after a hat-trick in the Phoenix's 3-2 A-League home win over Melbourne City last Sunday.
Krishna was named in a forward line comprising Mbappé, who has led Paris St Germain to the French Ligue 1 title, and Real Madrid's French international striker Karim Benzema.
Krishna's January Team of the Week colleagues included Barcelona's Luis Suarez, Manchester United's David De Gea and Liverpool's Fabinho.
His Phoenix teammates, Sarpreet Singh and David Williams, have also made FIFA Team of the Week selections in 2019. Singh, like Krishna, was a first-team selection while Williams made the reserve team.
Krishna has had his most productive season in the A-League.
He leads the Golden Boot scoring charts with 18 goals in 25 games - two ahead of Sydney FC's English import Adam Le Fondre.
Krishna has a chance to become the third Wellington Phoenix player to win the Johnny Warren Medal as A-League Player of the Year, following Shane Smeltz in 2008-09 and Nathan Burns in 2014-15.
The Fiji national team captain has been a regular selection in the A-League Team of the Week this season.
He was included in the Round 26 team after his three-goal haul against City with the A-League website noting: "Roy Krishna's evening will go down in Wellington Phoenix history.
"His first goal showed his explosive ability to destroy a defence on the counter-attack, with a deft finish thrown in. His second goal showcased his knack to create an opportunity for himself in a congested penalty area and add a killer finish. His third goal proved how lethal his instincts are in the six-yard box, improvising to scramble in a dramatic stoppage-time winner.
"Krishna set a new club record for goals in a Hyundai A-League season, he became the first Phoenix player to score 50 Hyundai A-League goals and he fired himself to the top of the golden boot standings. A good night's work by the Fijian flyer!"
