Madrid started the tie badly when, in the 6th minute, Bustinza scored the opener with a header.
Zidane's side then appeared to wake-up and it didn't take long for a response. Five minutes after going behind, they were level again thanks to Lucas Vazquez.
The winger reacted the quickest to a pass slipped through the Leganes defence and fired low across Cuellar beating the keeper just inside the left post.
