For me Alberto Costa still very raw, sometimes even clumsy. We should actually put a resale clause cause he is still young and Liga Sagres are great place to pump up players stats. Those mofo at EPL will get most of their data pop up from Portugal and bet high and we can get something from that
Joao seems more mature and ready to play even as a backup. Hearing that we reserve the non EU spot for Nahuel Molina, he will probably be the first choice for RWB with Joao as backup, both can be regularly switch so we can manage load better within all the competitions with lower quality drop
TIme will tell and welcome, good luck Joao
