Borussia Dortmund sailed into the last 16 of the Champions League after a comfortable 0-0 draw with Sporting in the second leg of their knockout play-off on Wednesday, giving last year's runners-up a 3-0 aggregate win.

Dortmund will now face either Aston Villa or Lille in the last 16, with their opponents to be drawn on Friday.

Despite trailing 3-0 from the first leg, Sporting showed little urgency in the early stages, preferring to sit back and wait for an opportunity to counter.

Sporting left top scorer Viktor Gyökeres at home as a precaution. The striker, who has scored 34 goals in 36 appearances this season, has been struggling with a thigh injury recently but played at the weekend and his absence was a sign of their resignation.

The hosts had the first chance of the game when Marcel Sabitzer tried his luck from distance but his shot flew wide of the far post.

Sabitzer, in search of his first goal of the season, then struck again from outside the area, this time forcing Sporting goalkeeper Rui Silva into action to push the ball away for a corner.

Dortmund were awarded a penalty 13 minutes after the break when Silva brought down Karim Adeyemi, but the Sporting keeper made amends by saving Serhou Guirassy's spot-kick to deny the Champions League top scorer his 11th goal of the campaign.

Substitute Giovanni Reyna had a glorious chance to break the deadlock for the hosts when he was sent through with only the keeper to beat, but he hit the post and could not convert the rebound.

Emre Can went close with a header but his effort was ruled out for offside as Dortmund, who have lost their last two league games, the first two under new coach Niko Kovac, continued their European march.

Sporting, meanwhile, continued their dramatic decline in form since Ruben Amorim left to take charge of Manchester United in November.

Under Amorim, Sporting won three of their four league games and finished second in the table.

Since his departure, they have failed to win a European game, losing five out of six, and their European adventure ended in anticlimactic fashion.
