In 2010, Lichiardopol conjectured for $q geqslant 3$ and $k geqslant 1$ that any tournament with minimum out-degree at least $(q-1)k-1$ contains $k$ disjoint cycles of length $q$. Previously the conjecture was known to hold for $qleqslant 4$. We prove that it holds for $q geqslant 5$, thereby completing the proof of the conjecture.
