Real Madrid slumped to a shock 1-0 defeat at CSKA Moscow in their Champions League Group G tie after falling behind inside two minutes.

Nikola Vlasic, on loan at CSKA from Everton, fired the Russians in front after 65 seconds. Real Madrid hit the crossbar in the first half through Casemiro, but despite plenty of second-half pressure the visitors, now winless in three games, could not find a way back into the match.

CSKA’s goalkeeper, Igor Akinfeev, was sent off for two yellow cards within a few seconds – both for dissent – during stoppage-time.

“Of course, [they] played at home and the quick goal helped them, but we didn’t take our chances,” said the Madrid manager, Julen Lopetegui. “We need to create scoring chances. I’m sure that sooner or later we will start scoring.”

The CSKA manager, Viktor Goncharenko, heaped praise on a “magnificent” Vlasic and CSKA’s defence. At the same time he was apprehensive over a possible ban for Akinfeev following his red card. “He is a half of our whole team,” he said.

Also in Group G, Roma thrashed Viktoria Plzen 5-0, with Edin Dzeko scoring a hat-trick.

Dzeko gave the Italians an early lead after just three minutes and added a second five minutes before the break.

Cengiz Under made it 3-0 after 64 minutes, with Justin Kluivert adding a fourth before Dzeko completed his treble with a header from a corner in stoppage-time.

Manchester United’s group rivals Juventus had little trouble against Young Boys in Turin. Paulo Dybala scored a hat-trick as Juve – missing Cristiano Ronaldo through suspension – continued their perfect start to the season.

The Bianconeri, who had gone into the fixture on the back of seven straight Serie A wins, took the lead after five minutes when Dybala crashed in a volley.

The Argentinian doubled the lead just after half-an-hour, knocking home a rebound from Blaise Matuidi’s shot, and completed his hat-trick after 69 minutes with a close-range finish.

The Swiss side finished with 10 men after defender Mohamed Ali Camara was sent off for a second caution with 12 minutes left.

In Group F, Lyon came from two goals down to draw 2-2 at home against Shakhtar Donetsk. Brazilian Júnior Moraes had struck either side of half-time to put the Ukrainian side in control. However, Moussa Dembélé started the comeback with 20 minutes left and defender Leo Dubois equalised two minutes later.

Ajax battled to a 1-1 draw at Bayern Munich to keep themselves ahead of the Germans at the top of Group E on goal difference. Mats Hummels headed Bayern into a fourth-minute lead but Ajax were level after 22 minutes through full-back Noussair Mazraoui.

In the same group, Benfica overcame the dismissal of defender Rúben Dias at the end of the first half to win 3-2 at AEK Athens.

Haris Seferovic put the Portuguese side in front after six minutes, with left-back Álex Grimaldo heading in a second on the quarter-hour mark.

AEK hit back with two goals in the space of 11 second-half minutes from striker Viktor Klonaridis to draw level just after the hour.

Benfica, though, got themselves back in front with 16 minutes left through substitute Alfa Semedo.
