In Mainz this weekend, where spring is reaching the trees but not yet the air, Nicolas Jackson scored the goal that began Bayern Munich's resurrection, but the Chelsea cloud continues to hover over him.
Three goals down after first-half goals from Dominik Kohr, Paul Nebel and Sheraldo Becker, the Bundesliga champions looked like a great machine stripped of animation; gears intact, movement absent, one eye on midweek.
Then, Senegal's Jackson struck -- meeting Konrad Laimer's cross in the 53rd minute -- and that grand old apparatus began to shudder back to life.
A second goal followed, a brilliant effort from Michael Olise, then a third, Jamal Musiala from close range, before Harry Kane secured a remarkable second-half comeback after capitalising on Daniel Batz's parried save.
