Prague - Achraf Hakimi scored twice to hand Borussia Dortmund their first victory in Champions League Group F as the Bundesliga side won 2-0 at reigning Czech champions Slavia Prague on Wednesday.
With 10 minutes remaining in the first half, Hakimi -- on loan from Real Madrid -- sprinted down the right flank, wove his way through the Slavia defence into the box, fooled 'keeper Ondrej Kolar and blasted home left-footed.
A minute before the final whistle, the 20-year-old Moroccan defender struck following another strong run and clinical finish with a low shot across goal.
With prolific striker Paco Alcacer ruled out with an Achilles tendon injury, Dortmund, who had drawn 0-0 with Barcelona at home in their opening game, started without a fully-fledged striker, relying on counter-attacks rather than constant pressure.
Captain Marco Reus started up front alongside Julian Brandt and English teenager Jadon Sancho, who went close with the first shot on goal in the second minute.
Sancho then set up the tireless Hakimi who fired wide, before playing a pass which a sliding Reus narrowly shot past a gaping Slavia goal.
Having reached the Champions League group stage for the first time in 12 years, Slavia, who held Inter Milan to a 1-1 draw at the San Siro in their opener, had a great chance on 20 minutes.
Lukas Masopust collected a pass that left him one-on-one with Roman Burki, but the Swiss 'keeper saved his poorly-placed effort.
Slavia's Romanian midfielder Nicolae Stanciu then saw his free-kick kept out by a diving Burki and centre-back Ondrej Kudela had an effort blocked by the visiting defence.
Sancho went clean through against Kolar early in the second half, but was denied by the Slavia goalkeeper.
Minutes later, striker Stanislav Tecl squandered a similarly clear opportunity for Slavia, firing wide as the hosts kept Dortmund under pressure.
Slavia midfielder Petr Sevcik then missed narrowly from long range, while Hakimi blasted at Kolar.
The game started with a standing ovation to the theme song for a German children's TV series sung by Czech pop singer Karel Gott, very popular in Germany, who died aged 80 on Tuesday.
In the other Group F game later on Wednesday, Barcelona will take on Inter Milan at the Camp Nou.
