Jarno Trulli has moved to defend his countryman Luca Badoer, following the Ferrari substitute's difficult return to Formula 1 in Valencia.
Badoer qualified last on the grid and has struggled to get on the pace all weekend. But the Toyota driver said that Badoer had faced an "impossible" situation, having not competed in a grand prix since Japan in 1999, and that Ferrari fans should not place high expectations on him.
"It's difficult to explain how difficult it is to drive a Formula 1 car if you don't drive it every week and every month," said Trulli.
Badoer has not tested the F60 properly this year, and only ran the car briefly in a promotional activity at Fiorano last week.
"I did expect him to struggle," said Trulli. "It's difficult for everyone to step into a car after such a long time out of the business.
"I think he is trying his best but he will need a bit more time definitely. More testing. I think it's hard. There is little we can judge about it in the end because it is obviously a very difficult situation.
"He has to enjoy what he is doing at the moment," added Trulli. "We are in the business and we all know how hard it is. People from the outside would probably expect more but it is impossible honestly.
"Luca was a good driver as well when he was driving, but being out of the business since 10 or 15 years is not ideal for you to jump in the car on a race weekend, which is very different from testing, without testing and without experience.
"I don't think he is having a lot of fun, but he needs to still do his job and do his best."
