Turin - Marco Reus’ first-half strike at Juventus FC on Tuesday could prove crucial in Borussia Dortmund’s quest to reach the UEFA Champions League quarter-finals for the third year running, according to BVB head coach Jürgen Klopp.

Reus struck after 18 minutes to cancel out Carlos Tevez’ opener and hand his side a priceless away goal in their last 16 first-leg tie in Turin, only for Alvaro Morata to slot home shortly before half-time and give the 30-time Italian champions the slenderest of advantages ahead of the return leg in Dortmund in three weeks’ time.

‘We know what we have to do’

“This result means we are still in the running, have kept things interesting and travel home with our heads held high,” Klopp told the assembled media at the post-match press conference. “Rarely have Juventus been put under as much pressure in their own stadium as they were by us in that first half. That shows us what we have to do against them in the return leg.”

Despite dominating for large periods of the game at the Juventus Stadium, BVB were unable to make the most of the goalscoring opportunities that fell to them, with Ciro Immobile and Mats Hummels both guilty of missing good chances after the interval. “After the equaliser I thought we could get more from the game,” said Reus, who scored his fourth goal in as many matches in Turin. “We were right in the game before we conceded a silly goal. Unfortunately, the equaliser didn’t help settle our nerves much.”

Piszczek injury blow

Dortmund’s cause was hardly helped by first-half injuries to key defenders Lukasz Piszczek and Sokratis Papastathopoulos, who both had to be replaced before the start of the second half in Turin. Poland international Piszczek suffered an ankle sprain and is likely to be sidelined for several weeks, while Greek centre-back Sokratis is also in danger of missing Saturday’s Revierderby at home to FC Schalke 04 with a muscle strain. “We hope [Sokratis] will be fit in time for the weekend,” said Klopp.

A 1-0 victory over the Serie A leaders in the second leg would be enough to secure die Schwarz-Gelben’s place in the last eight of Europe’s premier club competition for a third successive season and Reus, for one, is determined to make amends in front the Signal Iduna Park faithful on March 18. “Everything is still possible,” said the 25-year-old. “We have to make up for this defeat in the second leg.”
