Sochi's main stadium Fisht will be reconstructed to host FIFA 2018 matches by late January, Russian Sports Minister Pavel Kolobkov said.
"The expected completion deadline is end of January, 2017," the minister said.
Kolobkov added that the stadium will host 4 matches of the 2017 FIFA Confederations Cup in the summer. On March 28, a test match with a yet-to-be-named foreign team will take place.
Sochi, along with Moscow, St. Petersburg and Kazan, will host the 2017 Confederations Cup, a sort of rehearsal before FIFA 2018. One of the World Cup's quarterfinals will also take place in Sochi.
