Jude Bellingham hurled his arms in despair, Bayern Munich’s supporters hooted and hollered in disbelief but, through it all, Thomas Tuchel barely flinched.
What should have been the most challenging opening assignment for the former Chelsea manager – the ultimate showdown in Germany and, almost certainly, a title decider against his old club – turned into the kind of evening that he would have only thought possible in his dreams.
Bayern didn’t just beat Borussia Dortmund, they skewered them to such an extent you wondered how the team in yellow-and-black had arrived in Bavaria as the league leaders; how this hurt Bellingham, who at one point kicked a goal post out of sheer frustration.
