Carlos Sainz critical of Williams performance in Montreal

Carlos Sainz is clearly frustrated with the state of affairs at Williams after a brutal qualifying session in Montreal. He is set to start Sunday's Formula 1 Canadian Grand Prix from P15, a position that simply does not reflect the potential of the machine.

Sainz did not mince his words, suggesting the team is currently "underdelivering" on track. He insists that Williams needs to take a long, hard look at their data to figure out why they are punching below their weight when it matters most.
