This one also goes into the wall but nobody handles this time. And Lionel Messi blazes the rebound over.

No, it's straight into the wall. But wait the referee has given a handball decision against the wall. Javier Eraso was trying to protect his face and is booked.

And Lionel Messi gets another free-kick...

Lionel Messi has a free-kick from 25 yards. Can he score?

Athletic keeper Gorka Iraizoz pulls off a fantastic save from Luis Suarez's scuffed shot to keep his side level and Rafinha cannot turn in the rebound.

Athletic defender Gorka Elustondo actually does foul Luis Suarez this time and is booked.

Apparently that's the 14th penalty that Lionel Messi has missed in his career.

So 14 times that commentators have said something like "he is human after all".

Incredible - Lionel Messi's kick is saved by Gorka Iraizoz, who guessed right and went down low to his right.

Justice is done.

Harsh. Gorka Elustondo gets the ball but Luis Suarez goes down and it's a penalty.

Lionel Messi tries to drop a 30-yard cross over the top to Andres Iniesta but an Athletic player just about gets it clear.

Game has just settled down a bit. Barcelona having most of the ball but neither side creating chances at the moment.

Sergi Roberto, who is playing at right-back, puts in a cross. It went out of play first but the referee doesn't agree and let's play go on.

Then in the box, Gorka Elustondo handles the ball under pressure from Lionel Messi - but no penalty is given.

Both sets of fans angry there but in the end it evened itself out.

This is Barcelona's bench by the way; Ter Stegen, Bartra, Munir, Sandro, Camara, Gumbau.   

Not the strongest.  

Actually Dani Alves has gone down again and he's being replaced by Sergi Roberto, who is normally a midfielder. The Brazilian looks in agony on the bench.

He can. Dani Alves comes back on now. Relief for Barcelona who had been warming up a substitute.

Barcelona right-back Dani Alves appears to have hurt his groin after stretching for the ball under pressure. Will let you know if he can play on.

Gt Maestro:  Barcelona 4 V 0 Athletic Bilbao. Forget Supercopa de Espana. The real business just started.

Hemin Hassan:  I hope Messi scores four goals. 

Barcelona defender Javier Mascherano plays a pass back from the halfway line to goalkeeper Claudio Bravo. In England that would have got a round of applause.

Andres Iniesta, now Barcelona's full-time captain, goes down after a double-team tackle from Aritz Aduriz and Mikel Rico. 

Iniesta is fine though and Aduriz needs treatment but he is good to go again.
