Yuki Tsunoda says he is still at a loss of how to "extract performance" from his AlphaTauri Formula 1 car after a difficult Canadian Grand Prix weekend.
In a slow start to the season for AlphaTauri, Tsunoda has been a shining light, picking up their only two points with 10th place finishes in Australia and Azerbaijan.
The Japanese driver also has three 11th places to his name but had a quiet weekend in Montreal, having been knocked out in Q1 and then being unable to fight for points.

Tsunoda's troubles in Canada
Reflecting on his weekend, Tsunoda admitted that Canada was the first weekend of the season he "wasn't able to perform".
"It's a shame," he told the F1 Nation podcast.
"I'm pretty happy with the performance I did in the race, but I just have to put it all together.
"We definitely have to work on the qualifying pace. With the conditions we had, with the damp track, we expected to have a good qualifying, because FP3 in the rain was pretty good.
"We were comfortably top six, top eight (Tsunoda finished eighth), but qualifying was not what we expected and we struggled a lot.
"Even though the race pace was okay to be in the top 10, we started from P19 – which is not ideal.
"Everyone is in a DRS train, it is quite difficult to overtake here, so it didn't work in our favour and our strategy had a bit of bad luck as well."
