Good evening and welcome to Eurosport's LIVE coverage of the Copa del Rey semi final second leg between Alaves and Celta Vigo. We'll bring you all the action as it happens. Kick-off: 20.00.

Alaves have made history and they will play their first ever Copa del Rey final. They will play Barcelona and they deserved their win in the semi-final this evening. They were the ones on the front foot for the majority of the match and they scored a wonderful goal to make it through the tie.

FULL TIME: Alaves 1-0 Celta Vigo (1-0 on aggregate). ALAVES ARE INTO THE COPA DEL REY FINAL!

Can Celta Vigo create one final chance? Alaves have every single player back inside their own area, and for the moment they are managing to hold firm.

There's some argy bargy inside the Alaves penalty area after a Celta Vigo freekick drifts out for a goal kick. The away side know that as things stand they are crashing out.

So there is still plenty of time for Celta Vigo to get an equaliser here. That would be enough for them to move into the Copa del Rey final. Pellegrino is furious with the stoppage time.

Wow, we weren't really expecting that. There will be SIX minutes of stoppage time to be played at the end of the match.

There's another change from the away side and on comes Rossi. They now have four strikers on the pitch.

Celta Vigo are giving this everything they have got, pressing and probing on the edge of the Alaves penalty area. The flip side of that is they are leaving themselves open at the back.

It's the last chance saloon for Celta Vigo and so it's no surprise to see Berizzo throw on Guideti for the final few minutes.

They have been the better side in this second half and Alaves have found the breakthrough. The change had the desired effort and they are now on the brink of their first ever Copa final.

GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOAL! Alaves 1 (82' - Edgar Mendez) Celta Vigo 0. There's the goal that could decide this tie! What a sub! Edgar charges through the Celta Vigo defence, waits and chips his shot over Sergio. What a goal! How important could that be? It could be historic!

Celta Vigo didn't play at the weekend, so you would expect them to be the fresher side of the two if they are to enter extra time to decide this Copa del Rey semi final.

There's a change from the home side and Edgar wil play the final 10 minutes or so of this match.

STRAIGHT AT THE KEEPER! Wass got his head on the end of a cross into the Alaves penalty area, but he glancing effort only ends up in the gloves of Pacheco in goals.

Of course, one goal would mean there would be no extra time. At the moment we are heading for an additional 30 minutes. I'm not sure anybody really wants that.

Camarasa really has been superb this evening. Not only is he providing a real presence in the middle of the pitch, he is driving forward with the ball and starting attacks.
