Alonso expects new teams to speed up in 2011
Montezemolo insists that the grid should be filled by bigger teams fielding three cars, while struggling outfits like Lotus, Virgin and HRT "are supposed to race on Sunday mornings" in GP2.
The Italian also said Alonso's push for victory in Canada two weeks ago was ruined by the lapping of backmarkers.
Ferrari driver Alonso, 28, was asked by reporters about the comments at Valencia, but said he would have "nothing to say" about the slow teams in Friday's briefing with Charlie Whiting of the FIA.
"Next year I don't think we will see the difference that we've seen this year," he answered, referring to the difference in pace between the established and new teams.
"I think the three new teams arrived very late this year and I think next year they will be better prepared and the gap will be closer," added Alonso.
