Nash-Williams proved that for an undirected graph $ G $ the set $ E(G) $ can
be partitioned into cycles if and only if every cut has either even or infinite
number of edges. Later C. Thomassen gave a simpler proof for this and
conjectured the following directed analogue of the theorem: the edge set of a
digraph can be partitioned into directed cycles if and only if for each subset
of the vertices the cardinality of the ingoing and the outgoing edges are
equal. The aim of the paper is to prove this conjecture.
