On 7 August 2013, Khalifa was linked with a move to Marseille,[7] and he signed a four-year contract two days later.[8] He stayed one season, playing 28 league matches and scoring once.[5]
On 26 July 2014, Khalifa was loaned to Club Africain with an option to buy included in the deal.[9]
In June 2016 Kalifa was linked with a move to Qatar to play for Al-Shahania Sports Club but this move eventually fell through.[10] He spent time on loan with Kuwait SC in 2018.[3]
Upon signing with Marseille in August 2013, Khalifa's name was accidentally rendered as "Khlifa".[18] In a video for Marseille's WebTV, he attributed this spelling mistake to the misconceived pronunciation of his name when he arrived in France.[19]
