Do we really need Super Cups and Community Shields this season? Or the Carabao Cup? Or the Papa John's Trophy? Or the Nations League?

I could continue.

Great trickery from Barca winger Ousmane Dembele, who sends a defender down to the shops (for essential items only) with some quick feet but then his cross isn't good.

Unai Vencedor kicks over Lionel Messi, free-kick to Barca which doesn't come to much.

It's another big chance for the hosts! How are they not two up?

Romelu Lukaku finds space in the area to shoot after being found by Nicolo Barella pass. Lukaku doesn't catch his effort cleanly and Wojciech Szczesny easily saves.

A waste. Barcelona send Ousmane Dembele down the right but he overhits his cross and it runs out to Antoine Griezmann on the other side.

Cristiano Ronaldo is trying his luck from distance now as Juventus are struggling to break Inter down.

Serie A's top scorer, however, fires straight at Samir Handanovic. It's been a 36 minutes of few changes for the Bianconeri.

Decent effort from Athletic as Ander Capa's 20-yard drive is tipped over the bar by Marc-Andre ter Stegen. That's the first shot on target of the game.

Lionel Messi whips in an inswinging free-kick from deep... which is past everyone and Unai Simon has to save. It was a cross though.

Free-kick to Barcelona maybe 30 yards out... but they play it short before the TV director is even ready.

But they win another one in similar range.

Barcelona half-clear the corner and following ball into the box and eventually win a throw-in.

Romelu Lukaku's is proving to be a hand full for Giorgio Chiellini.

The Belgian is ever so silky as he spins his way past the Italian, who does well to scramble and recover on the edge of the area. A chance eventually presents itself for Lautaro Martinez, but it's wide.

Athletic win the first corner of the game as Sergino Dest blocks a shot. Can they load the area?

Juventus are lucks not to be two down in the first half hour, but they are regaining a sense of composure now.

They is plenty of intricate play from Andrea Pirlo's men, but they are lacking quality delivery into the box. Not for a lack of trying, however.

Jack Tanner: great shame the Supercopa isn't available to watch legally in the UK

Good move from Athletic down the left but Barcelona clear a cross away. The Basque side have been the better team in the opening 17 minutes.

Huge miss, this!

Lautaro Martinez really should have done better as the ball, from a Wojciech Szczesny save, rebounds into his path in the box.

There was no way back from Szczesny after he dealt with Romelu Lukaku's initial effort. Martinez, however, lacked the needed composure and sends his effort over the bar.

Inaki Williams is miles offside as he latches onto a long ball. He plays it to Raul Garcia, whose shot is straight at Marc-Andre ter Stegen.

And then the flag goes up.

Inaki Williams goes past Barcelona defender Clement Lenglet, who brings him down. Yellow.

Both goalkeepers get a chance to hold the ball as it goes end to end. There is a very annoying drone/heavy machinery noise at La Cartuja in Seville.

That opener has really given Inter some spark going forward. Nothing clear being fashioned, but they press with purpose.

Marcelo Brozovic takes a short corner on the left and thumps an effort on goal. Wojciech Szczesny easily gathers.

It's been an entertaining first 20 minutes.
