Everyone so sure he won't make it just because he doesnt play like Alba, Marcelo or didn't play better than everyone else when the entire first team stinked vs Levante, haha. Fact is he is by far the best LB in his age in Spain and has proven to be the same in youth EUROs and World Cups. Recently even had a run with an assist per game. He's a great defender as well. Some say he doesnt have pace, well not acceleration as Alba, but when he gets going he's very fast, like Mathieu. In terms of crossing he's already miles above Alba, every cross in any position or posture Miranda makes is a dangerous one, his left foot is heavy, so there's potential for him to become a great shooter of the ball as well. To add to it all, he's a good kid who works hard. He should be loaned back to Betis, his childhood club, for a couple of years where he'll become a starter at some point, hopefully prove himself and come back to Barca with confidence and the chance to succeed Alba who'll be reaching his final days at the top. There's no suggestion that he won't become one of the best left-backs in Spain, he's not like other fullbacks these days, he's not a small technician. He can be used in both the attacking Alba-role and in a defensive Abidal-role. The club sees a great talent in him and it's obvious. With his professionalism and minutes in La Liga in the next two years I think he can become a great, solid player that any club would want to have. As of now the only weakness of his is control in tight areas where he's a bit stiff due to his size.
