Sebastian Vettel says his new Ferrari team-mate Charles Leclerc will push him hard throughout this season. Leclerc, who has replaced Kimi Raikkonen, was told to stay behind fourth-placed Vettel in the closing stages of the Australian Grand Prix. Vettel said: "He'll put a lot of pressure on me the whole season. "It will be very close. He is very talented. I am sure we will have tough and tight battles but more than that I hope we have a lot of fun together."
