BERLIN – Borussia Dortmund kept a clean sheet in their impressive 4-0 Bundesliga win against fancied Bayer Leverkusen, which is good news for them ahead of Tuesday's Champions League opener against Barcelona.
"It was a good dress rehearsal. Against Barca we will also be without the ball for extended periods," midfielder Thomas Delaney said.
"It's important to keep a clean sheet. Ultimately, we win 99 per cent of our home games when we keep a clean sheet."
Even always-cautious coach Lucien Favre said "it is always good to win, also ahead of such a game," against the five-time European champions Barca.
Dortmund got back on track in the league after a surprise 3-1 defeat at promoted Union Berlin which had highlighted some weaknesses at the back and up front as well.
