Rather, the Italian sees momentum as a key factor in how the second half of the season will shake out.
“Spa is an epic track, one where you feel the driver can make a massive difference, and I want to start the second part of the season in the best possible way,” he said.
“We are motivated to set the tone right from the beginning of the run-up to the end of the year.”
Raikkonen, 41, is a four-time winner of the Belgian Grand Prix and returns from the mid-season break refreshed.
“I enjoyed the time off: spending this much time with the family is not something we do often so I made sure to make the most of it,” he said.
“Now, though, the holidays feel already in the past and I am looking forward to racing again: Spa is the perfect place to come back, it's a nice track where you get some good racing and Sundays can be unpredictable.
“The situation on track will be similar to before the summer: we need to be sharp and get the most out of our car and the circumstances and we can bring home a good result.”
Alfa Romeo is ninth in the constructors' standings on three points, ahead of Haas who is yet to get off the mark this season.
