European champions Real Madrid fell to a rare shocking Champions League defeat by CSKA Moscow in Russia.
Inside the opening two minutes Toni Kroos gifted the hosts their goal with a terrible backpass that was picked up by Nikola Vlasic, on loan from Everton, and he fired past Keylor Navas inside the penalty area to put CSKA ahead.
Karim Benzema, Casemiro and Mariano hit the woodwork for Real, as the Spanish side, without the injured Gareth Bale, pushed for an equaliser.
CSKA goalkeeper Igor Akinfeev was sent off four minutes into injury time for two yellow cards in quick succession for dissent.
Nevertheless, the hosts held on to move to the top of Group G above Real, who dropped down to second.
Roma beat Viktoria Plzen 5-0 in the other group game, but Real stay above them on head-to-head record courtesy of their 3-0 win over the Italian side two weeks ago.
