Fernando Alonso says he is concerned that Ferrari is slipping back as Formula 1 enters the second half of the 2014 season.
Ferrari has struggled with its recalcitrant F14 T this season and dropped to fourth place in the Constructors' championship after the German Grand Prix, in which Alonso finished fifth.
"At the moment we are not super happy with the performance, either him [Ferrari team-mate Kimi Raikkonen] or me, and we try to keep improving to score more points because, especially with the Constructors' championship, we are going backwards a little bit and we need to put both cars in the points as many times as possible," he said.
Alonso also downplayed hopes that Ferrari will make a step forwards at this weekend's Hungarian Grand Prix.
"Not really, obviously the car is identical with only four days between races and the circuit layout is not particularly good with a traction demanding circuit," said the Spaniard.
"On the other hand every race has been a little bit a surprise and at some circuits we thought we'd be more competitive and we were less and vice versa.
"We need to go into the weekend with some positive mood and see what is the final result, but the picture should not change compared to the last couple of races.
"Probably Red Bull will be more competitive with less engine demand here and we see Williams at a circuit that requires good traction and aerodynamics and we will see if they keep their form. It will be more or less similar."
