BRUSSELS, Belgium - Google Inc. is sure that its $3.1 billion bid for online ad tracker DoubleClick would now win over European and U.S. controllers as well, a company executive said Friday - even as advertisers uttered concerns the deal would contract competition.

However the European Union's executive arm has a Nov. 13 deadline to clear the deal or open a fuller examination, which could take up to four more months. It would not inspect the privacy concerns but stick strictly to how the deal affects the market.
