Lewis Hamilton believes Mercedes has now caught up with Ferrari after his team took a step forward in performance at recent races.
Ferrari's last victory came at the Monaco Grand Prix in May and since then Mercedes has secured pole position in every qualifying session and won three of the four races. It could have been four wins out of four had it not been for a loose headrest on Hamilton's car at the Azerbaijan Grand Prix, and the strong run of form has seen Hamilton close the gap to Vettel in the drivers' championship to just one point.
