Manchester City maintained their perfect Champions League record with a hard-fought win at Young Boys.

Erling Haaland scored twice in the second half, his first Champions League goals in six games, first with a penalty, then a fine curling effort.

Reigning champions City had dominated proceedings and led in the 48th minute when Manuel Akanji tapped in.

The Swiss hosts pulled level shortly after through Meschack Elia's exquisite chip.

But Haaland's 67th-minute penalty, followed by his second with four minutes remaining, ensured City remain top of Group G with nine points from three games.

"That is how it goes, if you don't take them chances it can be difficult," City defender Rico Lewis told TNT Sports. "In the end the forwards took their chances and we won the game."

Pep Guardiola's side are now unbeaten in their past 16 Champions League matches, winning 10 and drawing six, with only Manchester United between 2007 and 2009 ever having a longer run without defeat among English teams in the competition.

They led when Switzerland defender Akanji netted in his homeland from close range after Ruben Dias' header was palmed on to the crossbar by Young Boys keeper Anthony Racioppi.

City were pegged back in style when Elia was set free with a direct through ball to perfectly lob the stranded Ederson.

But Rodri was caught on the ankle by a clumsy Mohamed Ali Camara lunge in the box, which allowed Haaland to slam home from the spot and seal all three points in Bern - before he added gloss to the scoreline.
