We're under way at Signal Iduna Park.
Hello and welcome to the live commentary of the Champions League round-of-16 clash between Borussia Dortmund and Chelsea at Signal Iduna Park.
Dortmund advanced to the round of 16 by finishing in Group G behind Manchester City. Edin Terzic's men were solid enough to secure their place in the knockout phase, but will need to raise their game tonight against the Blues on home soil. Die Schwarzgelben have won their last six matches in a row in all competitions, including their 2-0 triumph over Werder Bremen last time out. They are in prime form, but need to deliver to take an advantage into the second leg.
Chelsea woes under Graham Potter continued last time out as the Blues were held to a 1-1 draw by West Ham United after taking the lead through Joao Felix. The Blues have won just one out of their last eight matches and need a positive result to stem the tide. Chelsea finished top of Group E, winning four of their six matches, so they have been playing well in the competition. Potter needs his side to forward a solid performance tonight to leave the contest in their hands for the return leg at Stamford Bridge.
BORUSSIA DORTMUND SUBS: Giovanni Reyna, Mahmoud Dahoud, Marco Reus, Mats Hummels, Anthony Modeste, Donyell Malen, Thomas Meunier, Julian Ryerson, Alexander Meyer, Tom Rothe, Jamie Bynoe-Gittens, Soumaula Coulibaly.
CHELSEA (4-2-3-1): Kepa Arrizabalaga; Reece James, Thiago Silva, Kalidou Koulibaly, Ben Chilwell; Ruben Loftus-Cheek, Enzo Fernandez; Hakim Ziyech, Joao Felix, Mykhailo Mudryk; Kai Havertz.
CHELSEA SUBS: Mateo Kovacic, Marcus Bettinelli, Trevoh Chalobah, Mason Mount, Denis Zakaria, Conor Gallagher, Cesar Azpilicueta, Carney Chukwuemeka, Marc Cucurella, Wesley Fofana, Lucas Bergstrom, Lewis Hall.
Graham Potter will be satisfied with his side's performance, although once again he will be crying out for a clinical edge. Joao Felix could have handed his team a crucial advantage, but more chances will be available for the Portuguese and his team-mates in the second half.
Dortmund are next in action on Sunday in the Bundesliga at home to Hertha Berlin. Chelsea play in the Premier League on Saturday against Southampton at Stamford Bridge.
