Two second-half goals in less than three minutes from Serge Gnabry and another from Robert Lewandowski earned Bayern Munich a thumping 3-0 victory at Chelsea in their Champions League round-of-16, first-leg at Stamford Bridge.

All eyes were on Bayern striker Lewandowski prematch, but rather than score the vital goals he set them up for teammate Gnabry to score twice early in the second-half.

A Cesar Azpilicueta slip let Lewandowski in on 51 minutes and he squared across the face of goal for Gnabry to score from close range.

And three minutes later the pair combined to devastating effect again for Gnabry's 17th goal of the season and his sixth Champions League goal in London this season.

By the time Lewandowski got his own name on the scoresheet with 15 minutes to play, thanks to great play by Canada international Alphonso Davies who registered the assist, the tie was as good as over due to Bayern's three away goals.

Bayern had been on top for much of the first-half as well, Willy Caballero, making his first Champions League appearance in almost three years, saving from Lewandowski on more than one occasion and Thomas Muller hitting the bar with a back-header.

By contrast Chelsea, who were reduced to 10 men when Marcos Alonso was shown a red card for a foul on Lewandowski, could only muster half-chances in their heaviest home defeat in European football.

As well as having to play the return leg without Alonso, Chelsea will also be without Jorginho after the midfielder was booked for dissent.
