It was all that was missing: a Lionel Messi goal. The rest of Saturday's Copa del Rey final was following a predictable, popular script.

Barcelona were winning. Athletic Bilbao were losing. Again.

For the second time this month, for the sixth time in succession, the final was a step too far for poor Athletic.

No club have won the Copa more times than Barca - this their 31st triumph - but for a long time that was a table topped by the team from Bilbao.

Athletic sit second on the list, with 23 wins, but none after 1983-84.

They beat Barca in the 1984 final at the Santiago Bernabeu and there has been nothing but misery for Athletic in their favourite competition ever since.

April 2021, with two opportunities, was surely the time for that run to end. But first they lost 1-0 to rivals Real Sociedad, and then, on Saturday, 4-0 to Barca. Again.

The run of six finals without a win is a new record, and four of the defeats have come at the hands of the Blaugrana.

And Messi had scored in each of the prior three.

Indeed, the Barca legend's very first final goal came against Athletic in 2009.

Messi played in Samuel Eto'o, saw his shot blocked and ran onto the rebound to put Pep Guardiola's side in front. They had trailed in that match and won 4-1, the first act of a stunning treble complete.

Three years later, the great number 10 was at it again.

He took Andres Iniesta's pass in his stride and rammed a right-footed finish into the roof of the net from a tight angle, the second of three Barca goals in the opening 25 minutes. A 3-0 win.

And then in 2015, perhaps Messi's best final performance of all. He scored twice and the first was one of the great goals.

The Barca forward took up possession near halfway on the left, invited in three Athletic defenders and then beat them all. Into the box he ran, skipping inside one last challenge before firing in.

So while losing to Barca - again - felt familiar for Athletic in Seville, keeping Messi at bay heading into the final quarter of the match did not.

Even then, from the fringes, Messi had still had a say in proceedings.

Following a tense first half in which the best opening saw Frenkie de Jong hit the post from Messi's pass, the Argentina international found his Netherlands counterpart again 15 minutes after the restart.

De Jong crossed and Antoine Griezmann, earlier denied from a similar position by the briefly inspired Unai Simon, made no mistake.

The second goal came from the other side. Jordi Alba crossed and Messi moved towards the ball, but it instead reached De Jong in the centre, stooping to nod into the net.

Messi had entered the match with 29 goals in 33 finals. His Copa record stood at seven in nine. With Athletic now all at sea, there was time left to boost those fantastic figures further.

Within five minutes of De Jong's header the chance came. Messi calmly controlled inside the area, created a yard of space and picked out the bottom-left corner with a gentle effort.

It was certainly a prettier goal than his next as Alba's cutback was sent goalwards and Simon, finally reading the script again, let Barca's fourth and Messi's second slip through his fingers - much like Athletic's hopes. Again.

Having helped their captain to a pair of goals to go away with, Barca's players made sure to secure souvenirs of their own as Messi posed for pictures with each of them alongside the Copa.

There is still a title to fight for in LaLiga before his contract expires at the end of the season and the rumour mill reopens for business, but this might have been Messi's last Barca showpiece.

On the periphery for over an hour, he wound up with a game-high six shots, three on target and two goals. If this was the end, Messi's final final, it was a fitting finish.
