Mourinho freezing in Moscow: -10 degrees is not the same as +15 © EuroFootball.com

Madrid strategist Jose Mourinho is worried about the weather in Moscow and the artificial grass of the "Luzhniki" stadium. On Tuesday, in the Champions League round of 16, the Spanish team will test their strength against the local CSKA, represented by Deividas Šemberas.

"Minus 10 degrees is not the same as plus 15," said the Portuguese. "Then you have to play on the artificial grass, which is not easy, especially in such cold weather."

Mourinho has previously expressed a critical opinion about artificial grass, but he was hoping for a positive result: "We want a victory or at least a goalless draw. The main goal is ultimate success and a ticket to the quarterfinals."

The Portuguese promised not to spare the players: "I don't think we will let some players rest because of the weather or the grass. We have a strong squad, so I will choose the starting eleven based on the opponent, not other factors."
