The Ferrari driver has moved to within 20 points of the front-runners following his controversial win in Hockenheim and a solid second place in Budapest, as Ferrari continue to make improvements to their 2010 car.
“It only took us two normal races to be fully back in contention for the title,” the Spaniard said.
“It’s true we are still behind in the classification and it is always better to be in front, but I am convinced that in the final sprintÃ¢â‚¬â€by which I mean the last two or three racesÃ¢â‚¬â€we will be closer to the top than we are now.
“Maybe, Hamilton, Button and myself, who have already won a title, will tackle the final rush in a calmer way having already experienced something similar.
“Percentage chance? I’d say 50 per cent, which is the normal state of affairs.”
AlonsoÃ¢â‚¬â„¢s point is a forceful one which will hit home at Red Bull. The Milton Keynes-based team have dominated the championship this year, but it is worth remembering that they have yet to win a titleÃ¢â‚¬â€something McLaren and Ferrari know only too well.
Despite their dominance in practice and qualifying, Christian HornerÃ¢â‚¬â„¢s team have failed to capitalise on their clear advantage in a number of races, and only regained the lead of the championship in Hungary after McLarenÃ¢â‚¬â„¢s worst weekend of the season.
Alonso added: “The car is much improved and so that makes me more optimistic and has seen the whole team grow in confidence.
“In Spa, we will have a few more things and we hope they help us progress still more: the others will do the same, which means we will have to be better than them and quicker in terms of development work.”
Ferrari face a World Motor Sport Council hearing on 8 September, just four days before the Italian Grand Prix, over alleged team orders which handed Alonso victory ahead of team-mate Felipe Massa at the German Grand Prix last month.
