Barcelona’s Ferran Torres scored one goal and assisted another as his side held off Shakhtar Donetsk to maintain their perfect Group H record in the Champions League.

The ex-Manchester City forward then set up Lopez for Barca’s second eight minutes later.

Heorhii Sudakov scored a second-half consolation goal but the hosts held on.

The five-time winners, who last lifted the trophy in 2015, are top of their group with nine points, while Shakhtar stay third, six points behind the La Liga champions.

Torres impresses before El Clasico

With usual centre-forward Robert Lewandowski out with an ankle injury, Torres made the perfect case to start up front in Saturday’s El Clasico league match against rivals Real Madrid.

The 23-year-old found the net in his second consecutive Champions League game, smashing a bouncing loose ball into the net.

He then received the ball on the turn and set up Lopez who brilliantly doubled Barca’s advantage with a fine strike which went in off the post.

Lopez also hit the woodwork in the second half and had a header ruled out for offside which would have restored his side’s two-goal lead in the 70th minute.

Shakhtar stunned their hosts, scoring on a rare break upfield, but never looked like adding a second to take a point from the Estadi Olimpic Lluis Companys.

Barcelona started 16-year-old Lamine Yamal for the second time in the Champions League, while 17-year-old Marc Guiu, who scored the winner on his debut against Athletic Bilbao on Sunday, came on as a late substitute.
