In her opinion in Ruiz Zambrano v Office National de l'Emploi (ONEm) (Case C-34/09) [2011] ECR I-01177 [Opinion ECLI: EU: C: 2010: 560], Advocate General Sharpston stated:

I regard the Court's description of citizenship of the Union in Gryzelczyk as being potentially of similar significance to its seminal statement in Van Gend en Loos that 'the Community constitutes a new legal order of international law for the benefit of which the States have limited their sovereign rights ... and the subjects of which comprise not only Member States but also their nationals.

Critically evaluate whether you agree with the above statement in light of the Court of Justice of the European Union's (CJEU) judgment in the Ruiz Zambrano case and in its subsequent case law.
