Sebastian Vettel says he will have mixed emotions when Lewis Hamilton secures his 91st win and equals Michael Schumacher's record of career victories in Formula One.
Hamilton heads into this weekend on 90 wins and as the favourite to win Sunday's Russian Grand Prix at the Sochi Autodrom.
Schumacher has held the record for most career wins since the 2001 Hungarian Grand Prix when he equalled Alain Prost's previous record of 51 victories. He went on to score another 40 wins by the end of the 2006 season - a record that Vettel, who made his F1 debut the following year after growing up as a Schumacher fan, thought would never be beaten.
