Ferland Mendy scored a stunning late winner as Real Madrid clinched a hard-working last-16 first-leg victory against 10-man Atalanta.
Real looked like being left frustrated by a well-organised home side until Mendy curled in with four minutes left.
Atalanta’s Remo Freuler was sent off after just 17 minutes for denying Mendy a clear goalscoring opportunity.
The depleted hosts did not have a single shot on target and now must score in the return leg on 16 March.
