Merengue beat Leipzig 1-0 in the first leg of the round of 16 series. In the first half, the local team suffered from the linesman's interpretation, which was validated by the VAR.

The clearest chance had been born from Brahim's vision, on the verge of half-time. It was confirmation that the worst for Real Madrid had already passed and he confirmed it at the start of the second act. The important casualties of Real Madrid were planned for the RB Arena.
