Ex-F1 ace Davidson: Massa is rubbish, useless.

Anthony Davidson has launched a stinging attack on former Formula 1 rival Felipe Massa, following the Brazilian's abject performance at Silverstone on Sunday that included no fewer than five spins en route to 13th place - and last - at the chequered flag.

Massa entered the British Grand Prix weekend as the world championship leader, but was trouble-afflicted form the word 'go' - culminating in a race showing that saw him the only driver to be lapped twice by race-winner and fellow title challenge Lewis Hamilton.

Davidson - out of work following the collapse of Super Aguri earlier this year, but bidding to find a way back into a race seat in the top flight once more - did not hold back in his criticism for the Ferrari star, particularly for what the Briton interpreted as a flagrant disregard for blue flags when being lapped.

"He's always the first to stand up in a drivers' meeting and complain about what people like me are doing when we get lapped," the 29-year-old is quoted as having said on BBC Radio Five Live during the race by the Daily Record.

"That's what you get, mate - there's a bit of blue flag action for you. You're rubbish. You are useless at it."
