Christian Horner once again took aim at rivals Mercedes, this time after Lewis Hamilton claimed a podium finish at the Canadian Grand Prix - his second of the season. After a difficult practice session on Friday, the Brit bounced back superbly to qualify fourth and finish third on race day.
Having suffered back issues due to the severe porpoising at the Azerbaijan Grand Prix earlier this month, the seven-time champion responded remarkably well. But throughout the season, the Silver Arrows have raised complaints about the impact the problem is having on their drivers.
Last week, the FIA announced a series of measures to reduce and hopefully eradicate the bouncing in the interests of safety. It came after other teams also spoke of experiencing the phenomenon in the new F1 cars. This seems to have angered Horner, who told Toto Wolff and his troops to focus on themselves before claiming they need to correct their own issues.
