Chelsea have been left with a mountain to climb after Bayern Munich handed them a 3-0 thumping at Stamford Bridge on Tuesday.

Serge Gnabry continued his knack of scoring against London clubs in this season’s competition with a second-half double three minutes apart against the Blues. The German international also scored four goals at Tottenham in the group stage.

Gnabry tapped in Robert Lewandowski’s cut-back for the opener before firing past Willy Caballero from a tight angle moments later.

Lewandowski then tucked in a third from close range, his 11th of the European campaign, before Marcos Alonso was sent off following a review by the video assistant referee as Bayern put one foot in the quarter-finals.

Elsewhere, Antoine Griezmann scored a second-half equaliser for Barcelona as the Spanish side grabbed a 1-1 draw in the first-leg of their last-16 tie against Napoli at the San Paolo Stadium.

Dries Mertens put the Partenopei ahead in the 30th minute before Griezmann tucked in Nelson Semedo’s centre in the 57th-minute to put Barca in good stead ahead of the return leg at the Nou Camp.
