1-He wasnt bad at all at this match,he played in the Xavi role,he showed some nice passes,his vision was good but he didnt do soemthing special and he needs time to do those specials like picking up a key pass or controlling the tempo of the match,for a midfielder,20 years old is too young to do those things,we have seen the best out of Xavi since he was 29-30 years old
2-another point is that playing with Xavi andf Busquetes is not like playing with Keita and Romeu,If Xavi was playing with the kid we could have seen a far better JDS,even if Xavi was off form,his name would get the best out of his partner
3-The Comaprison with Cesc makes no sense because when Cesc was 20,he has been playing foe 3 years at EPL,I think that JDS needs a loan movement rightnow because chances at Barca isn not like chances at Arsenal or any other team,however,I don think that JDS will reach Cesc's level but he has the potential to become a very good player,now he should go out on loan,if not he should train with the first team,get some minutes at weaker matches with Xavi-Iniesta playing with him and he should play week in week out with then Barca B.
