BERLIN (Reuters) - German Chancellor Angela Merkel said on Friday she could well imagine a European finance minister but stressed that the creation of such a position would have to be underpinned with reforms of substance.  We certainly need to strengthen the governance of the euro zone ... I have nothing against a European finance minister. I can well imagine that,  she told a joint news conference in Berlin with French Prime Minister Edouard Philippe.  But what is important to me is that we underpin the slogans -  economic government  and  European finance minister  and  budget  - with substance.  Merkel added that although monetary policy in the euro zone was harmonized, economic cooperation was still  incoherent.
