2) Henrik Mkhitaryan v Calum Chambers
Young Englishman Chambers has been filling in at right-back since Mathieu Debuchy, and has struggles against quick players like Swansea’s Jefferson Montero in recent weeks. Mkhitaryan has pace to burn but great ability with the ball at his feet too. With Marco Reus injured, the Armenian will be Dortmund’s main attacking outlet, and Chambers must shut him down efficiently.
