German Chancellor Angela Merkel said she still believes there is a chance the EU and U.K. would come to an agreement over Brexit, even as she stressed the importance of preparing for a collapse of the talks, Politico reported.

“The chance of reaching a good and sustainable exit agreement on time is still there,” Merkel said in a speech to the Bundestag, the German parliament, before heading to the European Council summit in Brussels, where leaders are set to try to resolve the remaining differences with the U.K.

Merkel said that a deal is in “our economic interest,” citing a call Wednesday from Europe’s car manufacturers on leaders to reach a deal.
