It's a poor corner, Sevilla break and Kevin Gameiro runs at Barca's defence. Jordi Alba is quicker than Javier Mascherano is so can win the ball fairly.
Just one minute added on, and Lionel Messi has a shot deflected wide for a corner. That corner will be the last action of the half.
Ten-man Barcelona have the chance to take the lead as Gerard Pique heads high and wide from Ivan Rakitic's corner.
Barcelona's holding midfielder Sergio Busquets appears to have dropped into defence now. Will Luis Enrique ponder a change at half-time?

Dave Wood: Stupid sendings off in cup finals are clearly all the rage this weekend
Viv: Very silly action from an experienced defender - JM. Clear foul on a clear cut goal scoring opportunity = a red!
dfoliver: Full marks to the referee, would have been easy enough to give a yellow. But red was the the right call.
Is this Sevilla's cup final to lose now?
And Sevilla nearly open the scoring from the free-kick. Ever Banega's brilliant effort is bound for the top corner but Marc-Andre ter Stegen tests his shoulder sockets to the limit and stretches his arm out to touch the ball over the bar.
A huge moment in the Vicente Calderon. Kevin Gamerio is on goal and Javier Mascherano tries to pull the shirt off him. It was a goalscoring opportunity so the Barcelona defender is sent off.
The offence was just outside the box so it's a free-kick, not a penalty.
Some of Barcelona's best passing of the game sees Dani Alves flick the ball to Lionel Messi, who plays it into Andres Iniesta. The Barca captain is in the box and but can't get a shot away.
WHAT A TACKLE. Adil Rami comes in with a head-first sliding tackle and takes the ball off Neymar.
The Brazilian isn't happy about that. Magic scenes.
Dani Alves almost opens the scoring from 30 yards out. The ball falls to the former Sevilla right-back, who lets it bounce and hammers in a shot which fizzes wide of the far post.
Barcelona are really struggling to get their game really going.

Gregory Mandapat: A domestic double is no small feat but with the popularity of Barca and Real Madrid, a loss and RM win next week is a failure.
George Chachanidze: When did being in a situation where you win the domestic title against Real / Atletico start to be considered unsuccessful...
Lionel Messi gets the ball well outside the box and the pitch opens up for him to have a cheeky little shot but he tries to find Luis Suarez instead and overhits his pass.
He should have gone alone.
Sevilla's Grzegorz Krychowiak has a couple of chances to shoot from 20 yards out but doesn't really get either of them right. Vicente Iborra is caught offside as he tries to get this head onto the second effort.
Sevilla boss Unai Emery will be delighted with his side's performance so far - they've matched their more expensive opponents all the way.
Sevilla have a big chance to open the scoring but Coke - who scored twice against Liverpool - fluffs his lines this time. He has a shot from 12 yards out but gets his calculations wrong. His effort using the outside of his boot is well wide.
Marc-Andre ter Stegen then does well to turn away a cross from his goal.
Has Barca's season been a success?
Andres Iniesta does a brilliant pirouette outside the box to keep the ball under control but then his pass is overhit to Neymar. The Brazilian gets onto it and tries a bit of skill himself, winning a corner - which comes to nothing.
There's not a huge lot of report on the pitch at the moment - a bit of pushing from corners, it's been a bit of a scrappy game.
Possibly a worrying stat for Sevilla - Lionel Messi has scored 25 goals against them to date - he hasn't scored more goals against any other club.
