  We introduce a gauge invariant topological definition of monopole charge in
pure SU(2) gluodynamics. The non-trivial topology is provided by hedgehog
configurations of the non-Abelian field strength tensor on the two-sphere
surrounding the monopole. It is shown that this definition can be formulated
entirely in terms of Wilson loops which makes the gauge invariance manifest.
Moreover, it counts correctly the monopole charge in case of spontaneously
broken gauge symmetry and of pure Abelian gauge fields.
