ARCALIS, Andorra, (Reuters) – Alberto Contador  stamped his authority on the Tour de France when he left Lance  Armstrong trailing in his wake following a bold, morale-sapping  attack in the final ascent of the seventh stage yesterday. Spaniard Contador made his move with some two kilometres  remaining in the 10.6-km climb to Arcalis and seven-times  champion Armstrong could not keep up the pace.

“There was no plan but when I saw that (Cadel) Evans, (Andy)  Schleck and the rest were not trying anything, I felt there was  an opportunity and I took it because I had good legs,” Contador  told reporters.

France’s Brice Feillu snatched a solo victory in the 224-km  stage from Barcelona ahead of compatriot Christophe Kern and  German Johannes Froehlinger.

Contador is now second in the overall standings, six seconds  adrift of Italy’s Rinaldo Nocentini, who took the yellow jersey  from Swiss Fabian Cancellara after being part of a nine-man  breakaway.

Armstrong, who started the day level on time with  Cancellara, is third, two seconds behind his Astana team mate  and rival.

“There was no real plan, it (the attack) was not really  expected but not surprising,” Armstrong, back on the saddle  after 3-1/2 years in retirement, told reporters.

“I feel quite good but it was not a steep climb.” However, the Texan would not concede defeat to Contador,  whose performance showed he can now demand to be Astana’s sole  leader.

“Like I always said, there is still a long way to go,”  Armstrong said, although he left the door ajar to Contador,  adding: “Like I said all along, I have to think about the team.

“Overall I feel pretty good, I’m not as knackered as I  thought I would be. Things did not quite go according to the  plan set earlier today but it was a fine day overall.”

CHASED BREAKAWAY    The question on everybody’s lips at the start of the stage  was whether Armstrong would claim the yellow jersey he last wore  on the Champs-Elysees in 2005 before retiring.

For a long time on Friday, it seemed he would fulfil his  dream as the favourites’ group perfectly chased the nine-man  breakaway. Australian Cadel Evans, twice a Tour runner-up, was  the first to try his luck but the Astana team did not let him  go. When Contador powered ahead without giving notice, the  favourites were left stuck on the tar and the Spaniard  accelerated twice more to discourage them from trying to catch  him.

Astana manager Johan Bruyneel said he wished Nocentini had  clinched the yellow jersey by a bigger margin as the AG2R rider  is likely to lose it in today’s second mountain stage,  putting the pressure of controlling the race back on the  Kazakh-funded outfit.

“Our plan was to let a breakaway go with someone in it  taking the yellow jersey,” Bruyneel said.

“We were hoping there would be bigger margins. Six seconds,  it’s not a lot.”

The escapees built a maximum gap of 12:30 but the pace in  the favourites’ group eventually proved too high.      “We had to set that pace to avoid attacks from Andy Schleck,  Cadel Evans, Carlos Sastre,” said Bruyneel.Levi Leipheimer and green jersey holder Mark Cavendish were  involved in a crash shortly before the last climb but they made  it unhurt to the line.    Among the favourites, Evans, defending champion Carlos  Sastre and Andy Schleck were part of an 11-man group that  crossed the line 3:47 behind Feillu — 21 seconds adrift of  Contador.
