BERLIN, Sept 29 (Reuters) - A top manager with Abu Dhabi's ADNOC expressed optimism on Monday about the European Union's ongoing review of its takeover of German plastics maker Covestro 1COV.DE but said there needed to be a balance between legitimate requirements and excessive demands.
"We are a strategic, long-term investor. That's why I'm actually very optimistic," Klaus Froehlich, ADNOC Group Chief Investment Officer, told Germany's Handelsblatt newspaper.
"There must be a balance between legitimate requirements and excessive demands. And of course, there's a limit for us as well," he said in an interview published on Monday.
