Toto Wolff warns Lewis Hamilton after Canada podium: 'One swallow doesn't make a summer'

Mercedes boss Toto Wolff has warned Lewis Hamilton that "one swallow doesn't make a summer" after the seven-time world champion secured his first podium in nearly three months at the Canadian Grand Prix.

Hamilton will head into his home race at the British Grand Prix a week on Sunday with renewed rigour after recovering from a back injury in Azerbaijan to finish third in Montreal - his best result since the opening round in Bahrain on 27 March.

Max Verstappen took the chequered flag to claim his sixth win in nine appearances and the sixth in succession for the world champion's in-form Red Bull team.

But Hamilton, already 98 points behind Verstappen in the standings, said he was "overwhelmed" to cross the line in third - a performance which gave the British driver hope that he could return to the winner's circle this season.

However, Hamilton and Mercedes were equally optimistic after his drive from the back to fifth position at last month's Spanish Grand Prix, only to be brought back to earth at the ensuing rounds in Monaco and Azerbaijan.

And team principal Wolff said: "One swallow doesn't make a summer. We saw that swallow in Barcelona, but somehow it flew somewhere else. We need to be careful. We were off the pace in practice on Friday.
