Wolff warns against too much euphoria: 'Canada was the odd one out'

It has taken a while, but at Mercedes the smiles are back. The last Canadian Grand Prix - in which pole was taken and a third place was celebrated - was proof that the German team is on the right track. In Spain, Mercedes wants to follow up the form from Montreal, according to Toto Wolff ahead of the Grand Prix at the Circuit de Catalunya near Barcelona.
