Formula One champion Emerson Fittipaldi has conceded his vision on Ferrari was 'wrong' having witnessed Red Bull's valiant comeback in the last two races at Imola and Miami. The title rivals took maximum points in Ferrari's home race with Max Verstappen winning the Sprint and the race itself, as well as securing the fastest lap, while Sergio Perez came in second.Similar success was enjoyed by Red Bull in Miami, where Verstappen won for the second race in a row and, while Perez could only come fourth following issues with his car, it left Charles Leclerc's lead at just 19 points but Ferrari's advantage in the Constructor's Championship lies in single figures.That has seen Fittipaldi rethink his assessments on the battle for the title after he admitted he never expected such a strong response from Red Bull following the Saudi Arabian Grand Prix.“I think I had the wrong opinion previously.
