Assume that f and g are continuous on γ, γ ⊂ ℂ is a piecewise smooth path parametrized by z (t) ,t ∈ [a, b] from z (a) = u to z (b) = w with w ≠ u, and the complex Chebyshev functional is defined by

In this paper we establish some bounds for the magnitude of the functional D γ (f, g) under Lipschitzian assumptions for the functions f and g, and provide a complex version for the well known Chebyshev inequality.
