Hola amigos! Welcome to live coverage of Stage 20 of La Vuelta - and it's the big deciding mountain test, a 190.4km schlep from Arenas de San Petro to Plataforma de Gredos.

Here's conformation of Roglic's Vuelta victory and Pogacar's spot on the podium.

So, Valverde will finish second in this Vuelta either side of the two Slovenians, with Quintana dropping off the podium and Lopez losing the white jersey.

It's the world champion Valverde who beats Rafal Majka and Herman Pernsteiner for second place around 1'45" down, while Roglic sits up and rides over in the knowledge that he has won the Vuelta.

The clock ticks away but Pogacar's fellow Slovenian will win this Vuelta now...

A third victory for the youngest rider of the race, Tadej Pogacar of UAE Team Emirates!

Another Slovenian stage win - and the overall for Roglic too...

Under the flamme rouge goes Pogacar, who is riding incredibly. He's 1'38" ahead of the chasing quartet of Valverde, Majka, Roglic and Pernsteiner. And another 20 seconds clear of the Lopez-Quintana group, so he will go back into white and onto the podium today.

Lopez back with Nieve, Kelderman, Quintana and some others in a chase group while Roglic, Valverde and Majka ride clear.

Still 1’35 for Pogacar. Behind, it’s all splintered with Pernsteiner putting in a series of attacks. Lopez has been dropped.

Pernsteiner opens up a small gap, covered by Grossschartner of Bora, for his teammate Majka.

Lopez, Valverde, Roglic and Quintana - in that order - until Movistar’s Colombian accelerates and comes to the front. Majka nips in ahead of Roglic, too. This group is still large with the likes of TGH, Hagen, Higuita, Kelderman and Pernsteiner in the mix.

In any case, it's now Soler on the front with Quintana, Lopez and Valverde behind. This red jersey group is thinning out.

The helicopter showed an attack from the chasing group - perhaps from Lopez - but there are no camers on ground level for the moment for some reason...

Still 1'35" for Pogacar.

We're onto the final climb of the day, the Cat.3 Plataforma de Gredos (9.4km at 3.8%). Our Slovenian man in front has 1'40".

We have just 10 competitive kilometres left of this Vuelta a Espana - and lone leader Tadej Pogacar is on a short downhill to the foot of the final climb.

Every little helps: Pogacar wins the intermediate sprint at Hoyos del Espino and pockets three bonus seconds ahead of the final climb. He then takes on a can of coke from a UAE soigneur, which he downs in a couple of swigs.

It's getting serious: Pog's lead is up to 1'45" and he could well knock one of the Movistar riders off the podium and snare Lopez's white jersey.
