Madrid - Borussia Dortmund head coach Jürgen Klopp says his side are ready "to go the extra mile" in the first leg of their UEFA Champions League quarter-final with Real Madrid CF at the Santiago Bernabeu on Wednesday (kick-off 18:45 GMT/ 20:45 CET).

Much has been made of die Schwarz-Gelben's injury epidemic this season, but the 46-year-old was in no mood for self-fulfilling prophecies upon touchdown in the Spanish capital.

'We can hurt them'


"Real Madrid have become more flexible and are better this year," Klopp explained, having masterminded Los Blancos' downfall en route to last season's final at Wembley. "I've watched them a lot, they've played a lot of games and I can't remember one where they didn't create many chances, but if they give us space, we can hurt them. Unfortunately we've got some injuries, but we're ready to play out of our skins."

Dortmund saw off Russian champions FC Zenit St Petersburg in the last-16, surviving a second-leg wobble to set up a repeat of last year's epic semi-final. For their part, Carlo Ancelotti's men were far more convincing in dispatching Bundesliga outfit and near-Dortmund-neighbours FC Schalke 04 to the aggregate tune of 9-2, but Klopp doesn't expect the same fate to befall his side in the last-eight.

'Really good players'


"We can be the biggest roadblock in the way of Madrid in the Champions League," warned BVB's affable strategist, before tackling the inevitable subject of leading scorer Robert Lewandowski's suspension. "Obviously it's tough not to have him on board, but these things happen," he continued."Now we've got to see what we can do about it [...] Often our playing style has helped us through difficult situations [...] We've got some really good players."

Marco Reus is widely expected to play the false No.9 role in Lewandowski's absence after helping himself to a match-winning hat-trick against VfB Stuttgart last weekend. "I'm happy to be playing again and will try to help the team get a positive result," explained the 24-year-old. "In the last few years, Robert [Lewandowski] has been the epitome of world class, but the coaching team will be prepared. Real Madrid have good individual players, but also have weaknesses. Our job is to exploit them."

Possible line-ups:

Real Madrid: Casillas - Carvajal, Pepe, Sergio Ramos, Coentrao - Modric, Xabi Alonso, Di Maria - Bale, Benzema, Ronaldo

Dortmund: Weidenfeller - Piszczek, Sokratis, Hummels, Durm - Kehl, Sahin - Aubameyang (Hofmann), Mkhitaryan, Großkreutz - Reus
