That's the question, why does Zidane/Madrid prefer Mendy and Marcelo over a 23 year who is supposedly this good. Is he crap defensively or physically not very imposing? You're saying it's addressed but giving preference as the reason.It's been mentioned a few times in the thread. They spent 45m euro on Mendy last summer. Zidane feels he prefers Mendy and Marcelo as his left back options. Madrid probably feel its one position where they can afford to sell in order to raise much needed funds. If they didn't buy Mendy last summer, I'm pretty certain this kid would be playing left back for them next season after his impressive loan spell.
