Vettel fastest in final Chinese Grand Prix practice

Red Bull driver Sebastian Vettel has continued to set the pace at the Formula One Chinese Grand Prix, clocking the fastest time in Saturday's final practice before qualifying.

Vettel was two tenths of a second clear of McLaren's Jenson Button, whose teammate Lewis Hamilton was third fastest.

Vettel's teammate Mark Webber had mechanical problems which restricted his running and the Australian was down in 15th on the timesheets.

Mercedes' Nico Rosberg was fourth fastest, ahead of the Ferrari pair of Fernando Alonso and Felipe Massa in cool but dry conditions at the Shanghai International circuit.
