Claire Williams isn't expecting any fireworks from Paul di Resta after the 31-year-old was thrown in at the deep end as Felipe Massa's replacement.

Massa suddenly fell ill yesterday, justifying a visit to the local hospital. But his condition did not improve overnight and the Brazilian ended prematurely his run in FP3 this morning.

A veteran of 58 Grands Prix, di Resta hasn't races since the 2013 Brazilian GP and has never raced a current generation hybrid F1 car, which makes his challenge all the more difficult admits Claire Williams.

"I'm sure he's probably fairly nervous," said Williams.

"But Paul is an experienced driver, and I couldn't feel happier actually that we have someone of Paul's calibre and experience.

"Even though he may not have taken part in a race weekend for a couple of years, he's driven this era's hybrid cars, he's driven in our 36, so I have confidence.

"Of course it's going to be tough. He hasn't had any practice, and he's got to get straight into qualifying in an hour's time.

"I'm sure there are some nerves there, he hasn't had much time to get ready, but I have utter confidence in him that if anyone can do this, Paul can."
