Primo : Barça's problem was not the Dutch players but only Van ghaal who pushed away the best Spanish players ( Sergi , Nadal ,Ferrer , Amor , Guardiola ...) and puted in some poor others (Xavi Gabri ...)
Secondo : I don't think that those 5 players can't be replaced
Tersio : Veron Sensini and Lopez all of them have are E U citizens
more Argentinians in the team are preferable than Brazilians or Spanish ... (but certainly not Italians)
'cause they can't be compatible to the Lazio players !
