Portugal have some interesting RB options and even some coming through the U-21 ranks and below as well.
Semedo's performances for the national team with his 6 caps weren't great, but it's likely down to the system as it's a lot different to what his style of play and skill set is. That's why Cedric Soares is currently a starter because he suits the system as he's a hard worker and it suits him.
Soares out of all the Portuguese RB's is easily the weakest in terms of talent and technical ability, but he makes up for it in heart and work. but I could see Semedo eventually overtaking him as Portugal's number #1 once he becomes more accustomed to Fernando Santos system.
