Mercedes boss Toto Wolff says the Canadian Grand Prix acted as “something of a🐟 wake-up call” for his team, despite claiming its seventh win of the 2019 Formula 1 season.

The reigning world champion squad extended its advantage in both world championships after a controversial penalty for Ferrari driver Sebastian Vettel handed Lewis Hamilton his fifth victory of the seasಌon in Montreal.

But Merce𝔉des’ weekend was hampered by a number of issues, including Hamilton making a rare mistake by crashing during Friday practice, as well as both cars suffering hydraulic leaks - the latter of which left the team with serious concerns over whether the Briton’s W10 would be ready in time for the race.

“Canada was something of a wake-up ca𓄧ll for us,” Wolff said.

“After a run of very good reliability over the opening six races, we experienced a number of problems over the course of the weekend, almost all of which were of our own making - from the problem with the fuel system on Valtꦦteri's car in FP1 to the hydraulic le🌊ak on Lewis' car which we had to fix on the morning before the race.

“We were fortunate that those reliability issues were exposed when we still had the chance to solve them, but we know that they could have easily ruined our weekend and it is down to t🎃he great skill of our mechanics that they didn't.”

Mercedes was the second-fastest team in Canada and Wolff is anticipating another close battle against Ferrari at this weekend’s French Grand Prix.

“We expect another tough fight in France,” he added. “The circuit features some🍎 si♋milarities to Montreal and the long straights will present a challenge for us.

“However, unlike Canada, the corner characteristics are spread across a range of speeds, which should play to our advantage. We're looking forward to the chance to put a few things right again.

“Part of our strength over the past three months was that the entire team - at the track, in Brackley and in Brixworth - delivered to a very high level and we need to make sure that we achieve the same hi🔯gh standard again for France.”

Hamilton holds a 29-point lead over Mercedes teammate Valtteri Bottas in the drivers’ stanꦆdings a𝄹nd is 62 points clear of Vettel, while Mercedes boasts a 123-point buffer to Ferrari in the constructors’.

Speaking about the increased threat from Ferrari in Canada, Hamilton said: “I hope this is a turning point for them [Ferrari] and this is going to be very close🦩 from now on and we get to have a really serious battle throughout the season. That would be fantastic.”
