Pep's City given a rude wake-up call

Everybody knows I'm a United supporter. To come here to win at City -- I've never lost here -- is very good for me.

Manchester City assistant manager Mikel Arteta admitted the English champions were handed a wake-up call in a shock 2-1 home defeat by Lyon to start their Champions League campaign on Wednesday.

Arteta took charge for the evening with Pep Guardiola serving a touchline ban for being sent-off in last season's quarterfinal exit to Liverpool. And Pep could only watch on in horror as Lyon punished a sloppy first 45 minutes through Maxwel Cornet and Nabil Fekir.

Bernardo Silva pulled a goal back in the second half but couldn't prevent City slumping to their first defeat of the season.

"When you are not at the races at the start of a game in the Champions League after, it doesn't matter how good you are, it is too late," said Arteta.

In contrast to their stunning domestic form, City have now lost their last four Champions League games.

Elsewhere, Gareth Bale scored as Real Madrid moved on from the departures of Cristiano Ronaldo and Zinedine Zidane with a 3-0 win over Roma to confidently launch their pursuit of a fourth successive title.

Isco curled in a terrific free-kick just before half-time at the Bernabeu, with Bale powering in a second and Mariano Diaz striking late.

"I thought the performance was very good tonight; the only disappointment was that we didn't score more," said Bale, who struck for the fourth time in five matches. "Real Madrid will always be Real Madrid, no matter who leaves."

Meanwhile, Paul Pogba was the driving force with a brace as Manchester United recorded a convincing 3-0 win away to Young Boys in Bern.

Skipper Pogba's superb opening goal cut down the Swiss champions in their prime, and he then doubled the English side's lead from a penalty just before the break.

The France star also set up the third goal for compatriot Anthony Martial in the second half.
