Again with the lack of arguments...
Of course i bring in Montoya he has in no way shown as much as Carvajal has and when he does play you can see Carvajal has a higher ceiling lol.
Lack of playing time for U-21's is a ridiculous singular way of seeing things, specially considering that you are ignoring what he HAS done lol. You forgot to learn how to build a football argument?
Fact of the matter is his performances were so good at age 20-21 for leverkusen that he was named bundesliga right back of the year and a very few handful rightbacks really shined in as bright as he did in 12/13.
id ask you to name a couple of better young right backs with clear foundations and evidence but i might as well ask you to fly right?
