Monreal had an extremely good performance against France with him and Jordi Alba Spain have nothing to worry about at LB.
And coincidentally the curse of right back seems to be ending soon as well. When Arbeloa's time comes to an end there is not one but several VERY talented right backs who can take his place.
-Azpilicueta is the oldest option but I still maintain that he is suspect in defense and more of a RWB which doesn't pair up well with Alba. He is very strong in attack though and can provide an extra dimension should they ever need it.
-Montoya, Mallo, and Carvajal are all of the same age and VERY talented in their own ways. Out of the 3, I'd have to say Carvajal is the best and a spot on the NT is very likely for him if he moves back to Madrid anytime soon. Mallo was better but I feel as if this long term injury is going to stunt his development.
-Manquillo is the youngest option at 18 and overall I'd say he combines both amazing potential bombing forward in attack as well as being disciplined and really solid in defense. Out of all 5 options, he has the most potential in my opinion as he is absolutely amazing all around and is efficient and fluid with the ball, like Filipe Luis. Although if any of the others secure an NT spot before him it will be horrible luck because he is definitely an amazing option. If he establishes himself with Atletico while they make their rise in European football,
