Well, it's unlikely but. With Doumbia back and with Honda and Dzagoev playing it won't be that easy for Real to win. CSKA have a very solid defense and now, with almost all players back, their attacking line looks good too. Honestly, I won't be surprised. It's almost impossible to buy a ticket to this game and 70000 or maybe 75000 fans will definitely help CSKA next week. It may look impossible for someone who doesn't know CSKA, but they are capable of almost anything.
Plus, it's difficult to tell how Real will perform in Moscow on synthetic pitch in cold weather.
