Felipe Massa insists that the fight for the 2011 F1 title is still very much wide open despite Red Bull dominated the season so far.

Sebastian Vettel has won five of the six races run to date while Red Bull have started every race from pole position.

Ferrari are already 129 points behind Red Bull in the constructors' championship while Massa sits eighth in the drivers standings but is 119 points down on Vettel. Team-mate Fernando Alonso is fifth in the championship, but is himself is 74 points down on the defending champion.

Despite that, Massa insists that Ferrari is still hopeful of challenging for honours when the season comes to an end even given the current dominance of the title holders.

"In the past, by the time you got to Canada, the shape of the championship was pretty much defined already, but now, as the calendar is so long, we cannot say anything is decided for sure yet," he said. "Everyone in Maranello is working flat out in their respective areas to continue improving the car so that myself and Fernando can race competitively, as we showed we could in the last couple of races, even if in terms of points, I have gone through a bad patch. I hope that will come to an end in Canada.

"As far as the championships are concerned, at Ferrari, we will never give up fighting. However, it is very clear that Sebastian is doing a great job, winning every race except one and even that time he finished second! He and his team are looking very strong, but we are tackling the championship one race at a time and everyone is still working very hard to make the car competitive so that we can continue fighting all the way to the end of the season."
