IT WAS GLORIOUS in its simplicity.

Devastating in its execution.

Robert Lewandowski won the header above Cesar Azpilicueta, directing it deftly towards teammate Serge Gnabry.

He then took one touch and returned the pass swiftly to the Polish talisman on the left wing.

Gnabry continued his run, Lewandowski played a perfectly-weighted through ball without flinching and the 24-year-old caressed his left-footed shot beyond Willy Cabalero.

Five touches were all that was needed.

Header. Touch. Pass. Pass. Goal.

Six seconds is all it took.

Six seconds from Lewandowski’s forehead to the the bottom far corner in front of the delirious Bayern fans.

Six seconds to end this Champions League last-16 tie as a contest ahead of the return leg in Munich next month, where Bayern hold a 3-0 lead and the visitors will be without Jorginho and Marcos Alonso due to suspension.

It was Gnabry’s second goal of the night – his sixth in the competition having netted four against Tottenham in London at the beginning of October.

It came barely three minutes after he tapped into an empty net when he and Lewandowski combined so brilliantly in the box.

A night of total domination was capped off with a quarter of an hour to go when Lewandowski was gifted a tap in of his own following a sublime solo run down the flank by left back Alphonso Davies.
