Rome, April 15 - Fernando Alonso has warned there will be tough times ahead for Ferrari despite the dominant style of his victory at the Chinese Grand Prix on Sunday. The Italian team got their strategy and the pit-stops perfect in a highly technical race and Alonso bounced back with an impressive drive after crashing out of the previous race in Malaysia. The excellent showing also confirmed that Ferrari's 2013 race car, the F138, is competitive. Indeed, Alonso said after the race that the F138 seemed to have some pace "in the pocket" when he was leading the field in Shanghai. Nevertheless, the Spaniard is refusing to get carried away with his first victory since July, as he knows the rival teams are working hard to catch up, especially three-time world champions Sebastian Vettel's Red Bull. "We need to be careful on that and maximise these type of weekends, when everything goes well, but I'm sure we will struggle on some other weekends and we need to maximise the points there," said Alonso, who also did well in qualifying to start third on the grid in Shanghai. "Sometimes we can win, sometimes the maximum is third or fifth but we need to do the job," added the driver, who climbed to fourth in Formula One's all-time grands prix winners' list with his 31st victory to move alongside Britain's 1992 champion Nigel Mansell. Alonso, who finished second in the season-opening Australian Grand Prix, is third in the drivers' standings with 43 points from three races, six points behind Lotus's Kimi Raikkonen and nine behind leader Vettel. His Brazilian teammate Felipe Massa climbed up to second early in China but got boxed in the midfield after a pit-stop and finished sixth. That contribution helped Ferrari cut Red Bull's lead in the constructors' championship to five points ahead of next Sunday's Bahrain Grand Prix. "I'm looking forward to next weekend because it's a very good test with very high temperatures and we will again see some problems and we need to deliver when the tough moments arise," said Alonso. "I expect a tough race again. In Bahrain I think we will see different conditions and who knows how competitive anyone can be. "But (we've seen) from the races that we finished this year that the car seems to be able to be on the podium, so we hope to be on the podium again in Bahrain".
