Michael Schumacher: I'm still in the Formula One title race

Michael Schumacher says he is still in the title race despite trailing leader Felipe Massa by 30 points ahead of Sunday's Chinese Grand Prix.

The seven-time world champion's return to Formula One has been disappointing with sixth his best finish from three races in his Mercedes.

"If we have quick enough development speed there's no reason why we cannot fight for the championship," said Schumacher.

"I'm pretty sure we have potential to develop this car. It's far from thinking this season is over for myself and [team-mate] Nico Rosberg."
