Montreal: One year after celebrating his maiden victory in Montreal Daniel Ricciardo admitted Sunday that he feels he is "banging his head against a wall" after finishing 13th in the Canadian Grand Prix.

The 25-year-old Australian started ninth on the grid behind his Red Bull team-mate Daniil Kvyat, but was unable to hold that position and finished behind Spanish rookie Carlos Sainz of Toro Rosso. "We tried and nothing worked," he said.
