Alberto Contador (Astana) pulled on the pink jersey at the end of the 19th stage to Monte Pora but now has just a four second lead on Riccardo Ricco (Saunier Duval) and 21 seconds on Danilo Di Luca (LPR).

Di Luca attacked over the top of the Passo del Vivione, 50km from the finish and joined up with team mate Paolo Savoldelli. They dived down the descent in the pouring rain with Vincenzo Nibali (Liquigas) hanging on.

Di Luca accelerated clear alone on the climb to the finish. He failed to catch Vasil Kiryienka (Tinkoff) who won the stage but finished second at 4-36. Alexander Efimkin (Quick Step) was third at 4-43.

Britain?s Steve Cummings (Barloworld) was fourth at 5-25 after being in the stage-long break.

Ricco stayed on Contador?s wheel for most of Di Luca?s attack but then jumped away alone in the final four kilometres of the stage. Despite a rear gear problem that stopped him using the 53 chain ring, the young Italian finished fifth at 5-44.

Contador got some help from the CSF Group team but struggled and finished 12th.

Di Luca gained 1-45 on Contador and Ricco gained 37 seconds.

Contador hung onto the pink jersey but is clearly worried Ricco and Di Luca could attack again on the final mountain stage over the Gavia and the Mortirolo and gain more time on Contador before the final time trial to Milan.

?It was a very long and difficult day,? Contador said before disappearing to his hotel for a warm shower.

?The stage was much longer than it said in the race manual and my team work really hard, I have to give them a ten out of ten.?

?I also have to say well done to Di Luca and Ricco, they made a good attack. The Giro is going to be interesting now??

?However I?m not scared of anybody I came to Giro with a plan. I?m not going to get obsessed about Ricco and Di Luca.?
