Fernando Alonso's lingering bitterness towards the McLaren-Mercedes team spilled over again in Budapest over the weekend as he said he didn't think he would be allowed to win if he was still driving for the British squad as their whole approach was slanted towards supporting Lewis Hamilton's efforts.

Alonso, who won the World Championship in 2005 and 06, was speaking on the first anniversary of his acrimonious split with McLaren in Budapest, a breach which ended with him rowing with chairman Ron Dennis and his right-hand man Martin Whitmarsh.

McLaren sources have since revealed that the Spanish driver was almost fired on the spot after deliberately blocking Hamilton during qualifying for the 2007 Hungarian grand prix, earning himself a five place grid penalty which dropped him from first to sixth in the starting order.

"If I was driving there for them this year it wouldn't make any difference because I would be in just the same situation as [Heikki] Kovalainen and not allowed to win," he said churlishly. "But I am much happier this year [at Renault] for sure."

Dennis, questioned on the matter, showed great dignity and restraint while at the same time letting it be known that all parties had agreed to a confidentiality clause precluding them from debating the matter in public.

And if Alonso couldn't keep his trap shut then the McLaren boss most certainly could.
