A substitute player scored two goals and added a late penalty, punishing the hosts for several wasted chances with a 3-0 win in their Champions League clash at Jan Breydel Stadium on Wednesday.

Last year's beaten finalists rode their luck but grabbed the lead when English winger Gittens, 20, picked up the ball on the left-hand side of the box and his angled shot took two deflections before ending up in the far corner of the net.

He ensured the three points with a second goal when he ran at the Brugge defense again, creating space to shoot and firing a low drive into the net for a superb solo goal.

Brugge will feel aggrieved as they struck the crossbar at 0-0 and had a couple of penalty appeals waved away but were also wasteful in front of goal, especially in the first half when they spurned several excellent chances.

The hosts were arguably the better side for 76 minutes until they conceded, and the confidence they had displayed up until then suddenly drained away.

'It wasn't a top performance but we took the win,' Dortmund captain admitted as his coach Nuri Sahin hailed his side's resilience.

'It was important to start with an away win against a tough opponent.

It was a good, attacking match from both teams.

In the end, with the changes we had, I think we deserved to win,' Sahin said.

Midfielder praised substitutes Gittens and Guirassy for their impact off the bench which turned the contest in the team's favor.

'It was tough in the first half.

We ran a lot,' Brandt told DAZN.

'It was a lot of work and a lot of attrition.

At the end, you could see that the spaces were getting bigger.

'Vetlesen hit the underside of the crossbar early on with a shot from six meters after Dortmund failed to clear a corner, leading to a scramble in the box in which Raphael Onyedika's shot was only parried by Gregor Kobel and the ball fell to Vetlesen, whose first-time effort came back off the woodwork.

Hans Vanaken blazed over when well placed and Vetlesen had another superb chance from a flowing Brugge move but his side-footed effort from 16 meters was well saved by Kobel.

After Gittens scored his first, Dortmund seized control of the contest and finished much stronger, adding a late third goal when Brandon Mechele felled Guirassy in the box and could have little complaint as referee Irfan Peljto pointed to the spot.

Guirassy confidently struck the spot-kick to add gloss to a scoreline that did not tell the full tale of the contest.
