Is there another manager who turns the Champions League knockout stages into an existential battle for his soul quite like Pep Guardiola?

The only time Manchester City appeared likely to win Saturday's quarterfinal against Lyon was when they looked like themselves: A dominant 20-minute, second-half spell that coincided with Guardiola abandoning an unfamiliar 3-5-2 shape in favour of their conventional back four, a sumptuous Kevin De Bruyne equaliser and concerted pressure thereafter. Yet, City went behind as a result of Guardiola's early conservatism and they were knocked out of the competition after losing 3-1 due to Lyon exposing the defensive vulnerabilities he hitherto sought to protect with his initial formation.

No wonder Guardiola looks so exasperated on these nights.

Guardiola and Manchester City will surely one day try to win the Champions League on their own terms, prioritising the free-flowing, expansive football that overwhelms so many weaker opponents. The need to do something different against better opponents on the biggest stage is seemingly a thought that consumes Guardiola on an annual basis.
