May 3 (GMM/Inautonews.com) Barcelona has opened the door to alternating its grand prix with F1’s other Spanish host Valencia.

But the Circuit de Catalunya organisers, set to run the Spanish grand prix next weekend, are determined to appear on the 2013 calendar, vowing to put tickets on sale the day after Sunday’s race.

“We will put the tickets (for 2013) on sale on 14 May,” Vincenc Aguilera, the new circuit president, is quoted by El Mundo Deportivo.

According to EFE news agency, however, Aguilera said alternating every year with Valencia is a “reasonable” proposition, given the current economic situation.

“In a crisis, during a storm, decisions should be conservative,” he said in Barcelona.

“We are getting all sides to reach an agreement,” he revealed. “It will take two, four, six weeks.”

Barcelona’s existing contract, for a grand prix every year, runs through 2016.
