On Thursday, Deutsche Bank <DBKGn.DE> Chief Executive Josef Ackermann, cast doubt on Greece's ability to repay its debt in a TV interview and said a $1 trillion euro zone rescue package will help stabilise Italy and Spain, while the situation in Portugal was more difficult.
Ackermann, one of Europe's top bankers, helped put together a rescue package for Greece.

WEAK EURO BOOSTS EADS
Among individual companies, planemaker EADS <EAD.PA> rose 2.8 percent, reaping the benefits of a weaker euro on Friday, as it forecast an eventual boost from Europe's sliding currency and predicting it would stay weak for some time.
Later in the session, investors will look at U.S. retail sales data for fresh insight on the health of the economy.
"If the U.S. retail sales were disappointing, the market could worry about final demand for a while," said McAlinden, adding: "Interest rates are low and earnings are good, so there should be a creeping tendency for markets to go higher".
