The Kazakh team will not be playing at the Astana Arena, as the games are scheduled to take place at Almaty Ortalyk Stadion.
Chelsea released this statement: “Renovation work on the impressive Astana Arena – which has a capacity of 30,000, a retractable roof and undersoil heating – has resulted in Astana playing their home fixtures elsewhere this season.
“They played their Conference League qualifying home matches against Milsami, Corvinul, and Brann at the Almaty Ortalyk Stadion – and that is where Astana will host Chelsea on Thursday 12 December.
“That fixture will be the Blues' final away trip of the league phase, which is now a single 36-team stage in which each side plays six fixtures (three home, three away).”
