BERLIN (Reuters) -Germany's finance minister has conveyed to Italy's Treasury his concerns about any takeover of Commerzbank by Italian lender UniCredit, two people familiar with the matter said, as Berlin looks to halt a hostile deal. Christian Lindner outlined his position to the Treasury - Italy's economy and finance ministry, led by Giancarlo Giorgetti - in tandem with German Chancellor Olaf Scholz's public criticism this week of UniCredit's move to become the biggest investor in its German rival.
