I'm going to leave you there for the night. Thanks for joining me this evening and getting involved in the debates.
- Suarez scores from Coutinho and Messi passes
- Messi slams home from Alba backheel
- Iniesta scores after Messi one-two
- Coutinho scores penalty after handball
- Barca win Spanish Cup for fourth consecutive year
Barcelona have put up a clip of Andres Iniesta lifting the trophy - you might need to click on the link below to see it.
Andres Iniesta goes to shake the hands of all the officials as he goes to get the trophy. And he lifts up the Copa del Rey to an explosion of noise from the crowd.
It's the fourth season in a row they've won this trophy. But it will be his penultimate Barcelona trophy, with La Liga set to be confirmed in the next eight days (possibly tomorrow if Atletico Madrid lose).
Sevilla boss Vincenzo Montella may not have won a major trophy as a manager yet. But at least he's always got the 1995–96 Anglo-Italian Cup winners' medal. His Genoa beat Port Vale 5-2 in the final.
(To be fair, he also won Serie A with Roma as a player).
I know Philippe Coutinho is seen as Andres Iniesta's replacement but think Barcelona need to buy some decent players this summer. They're short on quality beyond the first XI, Denis Suarez, Andre Gomes etc.
Fish Hailu: Again Ronaldo Messi topic. One is winning Copa del Rey while the other is set for Champions League semi final & probably win it three consecutive finals. Stats show that Ronaldo is better player than Messi.
Can we not just enjoy watching both of them? I like them both
Ayo Obit: Third Spanish Double in four years, one was a treble! Amazing! Yet some would say Real Madrid have had a better last four years than Barcelona.
A great noise at the Wanda Metropolitano as Barcelona celebrate their 30th Spanish Cup.
Sevilla fans have stayed behind to watch on too.
It's all over - Barcelona have won the Copa del Rey for a fourth season in a row.
Ousmane Dembele pulls the ball back to Luis Suarez, who snatches at a shot and it goes wide.
Andres Iniesta looks emotional on the bench.
What are Barcelona going to do without him? It just won't be the same.
A standing ovation from both sets of fans. Andres Iniesta comes off in what is probably his last Barcelona final. An absolute masterclass from him tonight.
He takes his time but you can't blame him, hugging a lot of players.
Then silence as Denis Suarez comes on!
Think the scoring might be over now. It's just petering out a bit.
Anon: In Messi or Suarez’s position Ronaldo would have taken that and ran to the corner with his shirt off trying to claim all the glory for himself. That’s why I don’t respect Ronaldo. With Barcelona it’s about sharing the glory together as a team.
Actually Ronaldo let Benzema take a late penalty in February to boost his confidence when he was on a hat-trick...
Both sides make a change. Philippe Coutinho comes off to a good ovation and he's replaced by fellow £100m+ player Ousmane Dembele.
Sevilla replace Pablo Sarabia with Miguel Layun, once of Watford.
This will be eight games without a win in all competitions for Sevilla.
Luis Suarez hasn't had many chances to get his hat-trick, but he has one here. He wins the ball off a Sevilla player and curls the ball towards goal but it's easily held by the keeper.
Harry, Edinburgh: It's times like this when I wonder how people can think more of Ronaldo than Messi! Messi is the ultimate team player!
Sam: Beyond copa del rey-son how good barca are.
Sevilla having a couple of shots, Ever Banega fires one over from range. Jasper Cillessen had a simple save to make a minute ago.
A Sevilla comeback here would eclipse Roma and everything we've ever seen in football before, I think...
Barcelona bring off Sergio Busquets, perhaps to avoid a possible red card, and Paulinho - who has proved a lot of people wrong this season - comes on.
Wonder if he's been giving Andres Iniesta tips on China.
Barca midfielder Sergio Busquets slides in on Franco Vazquez - a proper hack. Vazquez has a moan and they both get booked.
Sevilla fans are still trying to enjoy themselves and are doing the Poznan. Added bonus of that is they don't have to see what's happening on the pitch...
This is really nice by Barcelona. They win a penalty as Luis Suarez flicks the ball onto Clement Lenglet's hands. Philippe Coutinho slams the ball into the net but the referee gives the penalty and not the advantage.
Does Luis Suarez take it for his hat-trick? Does Lionel Messi take it for yet another goal? No, they let Coutinho take it since he was just denied a goal and he sends keeper David Soria the wrong way.
Andres Iniesta's passing stats must be off the charts tonight, he's at the heart of everything - spraying balls around the gaff.
This is a real Andres Iniesta masterclass. Imagine how much he is going to run the Chinese Super League. He finds Lionel Messi, and is fouled after releasing the ball but the referee says no... and books Iniesta for dissent.
When I say dissent, I mean a bit of a moan - not Gianluigi Buffon levels.
This is Sevilla's big chance but former Barcelona forward Sandro - on loan from Everton - shoots straight at Jasper Cillessen. Waste.
You know it's a party when Sergio Busquets has a shot. The Barcelona midfielder's 20-yard effort is deflected wide. He's only scored 13 goals in his career.
Barcelona are picking Sevilla apart at will now. An excellent move fizzles out before Philippe Coutinho heads off target. This could be six or seven if Barca want.
Andrew Reyes: This is simply no longer a contest. Barca on another planet tonight
Lionel Messi is the first player to assist in three consecutive Copa del Rey finals in the 21st century (five assists).
It's so close to a fifth goal from Barcelona. Excellent keeping by David Soria keeps them out.
Lionel Messi plays in a free-kick, hat-trick chaser Luis Suarez heads towards goal but Soria saves it. Samuel Umtiti looks to turn the rebound home from six yards out but the keeper is there again to deny him.
It's probably his last cup final before moving to China and Andres Iniesta has 100% wrapped up this Copa del Rey final.
Luis Suarez gives the ball to Iniesta, who finds Lionel Messi. The Argentine waits for Iniesta to make his run and picks him out. Iniesta then steps around the goalkeeper and taps the ball home.
Barcelona are just in cruise control at the moment. You feel a Sevilla goal would jolt them awake again though.
Philippe Coutinho overruns the ball down the right side after good work from Lionel Messi.
Barcelona left-back Jordi Alba has injured himself while blocking a Franco Vazquez shot - it was brave as he threw himself at the Sevilla player. He's OK to continue though, hobbling around.
Sevilla on the attack early on and have a couple of decent crosses. Much brighter, they looked totally beaten at the end of the first half
Is there any way back for Sevilla? Let's find out. The second half has started.
Sevilla make a change at half-time as Sandro, on loan from Everton, replaces Joaquín Correa.
