The German international sustained the injury as Cristiano Ronaldo scored his hat-trick in extra time, with Marco Asensio scoring shortly afterward to complete a 6-3 aggregate victory.

Neuer remained on the pitch for the rest of extra time but was in clear discomfort and hobbled down the tunnel after the full-time whistle.

Real Madrid 4 Bayern 2 player ratings Show all 22 1 /22 Real Madrid 4 Bayern 2 player ratings Real Madrid 4 Bayern 2 player ratings Keylor Navas – 6 out of 10 Found wanting when called upon. Should have done better to prevent Ramos’ own goal. Real Madrid 4 Bayern 2 player ratings Dani Carvajal – 7 out of 10 His early effort from range may not have gone in but it set the tone for Madrid to have the better of the first half. Real Madrid 4 Bayern 2 player ratings Nacho – 7 out of 10 More solid than his defensive partner, and looks to be benefitting from gaining Zinedine Zidane's confidence. Real Madrid 4 Bayern 2 player ratings Sergio Ramos – 6 out of 10 Unfortunate to divert the ball into his own net, but it could have been avoided with a little more communication. Real Madrid 4 Bayern 2 player ratings Marcelo – 9 out of 10 Excellent. Superbly blocked Thiago’s effort early on, then produced a brilliant goal-line clearance after the break to deny Robben. Impressed going forward too, setting up Ronaldo in extra time. Real Madrid 4 Bayern 2 player ratings Luka Modric – 7 out of 10 Key to Madrid’s excellent spells of first half build-up. Ronaldo should have rewarded one particularly special pass with the goal it deserved. Real Madrid 4 Bayern 2 player ratings Casemiro – 7 out of 10 Careless in his challenge on Robben for the penalty. Otherwise, a solid presence disrupting Bayern’s forays forward. Real Madrid 4 Bayern 2 player ratings Toni Kroos – 5 out of 10 Struggled to match the influence of his fellow midfielder Modric. Real Madrid 4 Bayern 2 player ratings Isco – 6 out of 10 Failed to build on Saturday’s excellent showing at Sporting. Real Madrid 4 Bayern 2 player ratings Karim Benzema – 5 out of 10 Offered very little before being hauled off for the more impactful Asensio. Real Madrid 4 Bayern 2 player ratings Cristiano Ronaldo – 8 out of 10 A quiet start but then came another ‘clutch’ goal, just like his two in Bavaria. Two more followed thanks to poor officiating, but this was still a reminder that you should never write Ronaldo off. Real Madrid 4 Bayern 2 player ratings Manuel Neuer – 6 out of 10 Will be disappointed to have conceded six over the two legs, but was outdone by some poor officiating here. Real Madrid 4 Bayern 2 player ratings Philip Lahm – 6 out of 10 Struggled to cope with Marcelo, who got the better of him too often. We have come to expect more. Real Madrid 4 Bayern 2 player ratings Jerome Boateng – 7 out of 10 Heroic block on the line stopped Ramos from putting the hosts in front in the first half. Real Madrid 4 Bayern 2 player ratings Mats Hummels – 8 out of 10 Another defender who put his body on the line when it counted. Spectacularly blocked Kroos’ shot in the first half. Real Madrid 4 Bayern 2 player ratings David Alaba – 5 out of 10 His poor crossing let his teammates down when they were making headway early on. Real Madrid 4 Bayern 2 player ratings Xabi Alonso – 5 out of 10 Surprisingly poor in possession during his last Champions League appearance, with several wayward passes. Replaced by Thomas Muller deep into the second half. Real Madrid 4 Bayern 2 player ratings Arjen Robben – 8 out of 10 Made things tick in Bayern’s attack. Questionable role in the penalty, maybe, but his side's stand-out performer still. Real Madrid 4 Bayern 2 player ratings Arturo Vidal – 4 out of 10 His tackle was fair and should not have resulted in a red, but still, too often a liability. Should also have done better when slipped in by Robben soon after Bayern’s first goal. Real Madrid 4 Bayern 2 player ratings Thiago – 5 out of 10 Off the pace in the opening stages and failed to grow into the game. Real Madrid 4 Bayern 2 player ratings Franck Ribery – 5 out of 10 A fading force, unfortunately. Simply did not trouble Madrid’s backline with the regularity of Robben. Withdrawn for Diego Costa. Real Madrid 4 Bayern 2 player ratings Robert Lewandowski – 6 out of 10 Not his best night, despite cooly converting the penalty.

“Manuel Neuer suffered a fracture to his left foot in the 4-2 defeat away to Real Madrid according to an initial diagnosis,” the club later said on their website.

“Neuer will undergo a thorough examination on arrival in Munich prior to a decision on the appropriate treatment.”

The 31-year-old had only just returned from injury after missing three Bundesliga fixtures last month.

A training ground injury necessitated minor foot surgery, causing him to miss matches against Augsburg, Hoffenheim and Dortmund.

His absence was keenly felt: Hoffenheim beat Bayern to end their 20-match unbeaten run with deputy goalkeeper Sven Ulreich unable to keep out Andrej Kramaric’s early half-volley.

Bayern have a maximum of seven matches remaining this season provided they beat rivals Borussia Dortmund in the German Cup semi-final.
