#2 Doubling up on a makeshift right back

Dani Carvajal is out of contention for the second leg and Achraf Hakimi is not included in the match day squad. It means that Real Madrid will most probably start with Lucas Vazquez at the right back position. Nacho is included the squad but his situation is said to be touch and go.
He has been injured for a month now and hasn't trained with the first team squad at all. It does not seem plausible that Nacho will straightaway be thrown into the mix in such a big game without any sort of match fitness.
This means that Vazquez, a winger, will probably be Real Madrid's right-back tonight.
Bayern Munich can target him on the night and can use the right flank as brilliantly as they did in the first leg. If Franck Ribery replicates his first leg form,there is every chance that Vazquez will be in for a long night.
Also, David Alaba is fit enough to start tonight! This means that Bayern will have the deadly duo of Alaba and Ribery on the left wing that has been tormenting defenders for quite a long time now.
By overlapping Ribery or by getting into the midfield spaces to dominate the area with numbers, Alaba plays a huge role in Bayern Munich's attacks. Real Madrid have their task cut out to keep not one but two left-wing tormentors in check.
