Generally, foreign leaders don't criticize other nation's electoral candidates. The logic is simple: This person might win and you don't want your witty insult from a year prior hanging over you if you have to work together. This tradition hasn't continued with Donald Trump. A range of foreign leaders past and present have publicly expressed doubts about Trump and his proposals; others have spoken off the record to more candidly explain their angst at the thought of a President Donald Trump.
