Amid the carnage it was barely noted, but in the first half as Bayern Munich played Arsenal came a moment that surely holds the key to it all for Pep Guardiola.
Manuel Neuer collected a back-pass just outside his penalty area, to the right of the D. He controlled it with the outside of his right foot. Alexis Sanchez came in to close him down. Neuer took it further right, still outside the area, towards the corner tip.
As Sanchez increased his pace, Neuer looked up — that’s important — and unloaded a 50-yard pass, which dropped on to the chest of Arjen Robben, inside the Arsenal half.
