It all looked so promising when Kyle Edmund beat Feliciano Lopez in straight sets to put Great Britain into an early lead in this semi-final, but when Rafael Nadal hit back against Dan Evans it meant an all-or-nothing doubles decider in Madrid.

And it was Spain who came out on top, winning both sets on a tie-break to reach the final on home soil, where Canada await after seeing off Russia earlier today.

We'll be back tomorrow...

And here's Feliciano Lopez: "A lot of drama today on the court. It's 1-1 and the winner goes to the final here in Madrid...

"A very special moment, a unique opportunity and we are very pleased we somehow managed to play all those points in a good way.

"Rafa hit an unbelievable lob when we were down in the break 6-4. We are really happy and have a great opportunity to hold this trophy tomorrow."

Spain's world number one Rafael Nadal: "This competition is dramatic and with this new format even more.

"It was very close. We played a great match. In the important moments Feli did everything well. We are super happy. I just want to say thank you very much to the team and to the crowd."

Rafael Nadal drops to the floor. Andy Murray looks on in disbelief.

It's Spain, the hosts, who will be back to face Canada in the Davis Cup final on Sunday.
