I wouldn't give Xavi control over everything.
He will probably buy 11 Puigs/David Silvas, lol. He is stuck in 2010'.
About Jordi or Kluivert, I was never impressed by Jordi as a footballer. He was average and a choir boy.
While Kluivert was a rockstar.
Kluievrt isn't mentally strong as Rijkaard or Lucho, but I would pick him over Xavi, Jordi, Pimienta or Setien.
He was coached by Van Gaal, Rijkaard, Hiddink.
He played for Barca, Ajax, Milan and Dutch NT team.
He has Dutch and Barca connections and probably knows a lot about total football (from Ajax, Barca and Dutch NT).
Also, he was an attacker, so it is more likely that he would set up a more attacking tactics than some former fullback, defender or a GK.
As Khaled said, it we pair Kluivert with an experienced assistant, I would rather give him a chance in last Barto's year.
And since he was a true, good, old No9, maybe he would save us from buying clowns like Lautaro or Gabriel Jesus.
For younger fans, best of Kluivert. He scored a CL winner for 1:0 (Ajax:Milan) in 1995, aged 19, in the 85th minute.
The same Milan who won 4:0 against Barca in 1994's final.
Later he played 6 years for Barca as a NO9 and scored 122 goals in 257 matches. And scored 24 CL goals in Barca's 4 CL seasons during his era.
Btw, last 3 Dutch coaches for Barca:
Cruijff, 4 La Ligas, 1 CL
Rijkaard, 2 La Ligas, 1 CL
Van Gaal, 2 La Ligas
