  We report on the interesting possibility of instanton-driven gluon saturation
in lepton-nucleon scattering at small Bjorken-x. The explicitly known instanton
gauge field serves as a concrete realization of an underlying non-perturbative
saturation mechanism associated with strong classical fields. The conspicuous,
intrinsic instanton size scale known from lattice simulations, turns out to
determine the saturation scale. The ``colour glass condensate'' can be
identified in our approach with the QCD-sphaleron state, dominating
instanton-induced processes in the softer regime.
