90'+3' And that's it! GAME OVER!
90'+3' Messi makes a run through the middle. He wriggles past a couple and then gets taken down but it was fair.
90'+1' Messi wins a corner for Barcelona as we enter stoppage time. Three minutes to play.
88' Fabian with a chance. Sergio Leon loses out but it falls kindly to the sub. He blazes over and Ter Stegen still doesn't have to make a save.
86' Lucas Digne replaces Jordi Alba. Big round of applause for the left-back.
85' Very little to be gleaned from this for Barcelona. The second half has been a walk in the park.
83' Messi with another shot. Adan saves.
82' Change for Barcelona. Alcacer replaced by Denis Suarez.
81' Messi hits the woodwork again. Wow. This one was more of a rasper, technically, than a curler but still. Very unlucky.
80' Real Betis 2-0 down and they are sitting back and waiting for Barcelona to make a move. Strange decision by Quique Setien.
78' Camarasa suffering from the August heat in Barcelona and the work he has put in. He goes off with cramp for Fabian.
76' Nelson Semedo breaks free and plays a lovely pass in behind Real Betis back four. They manage to get it away but what a run by Semedo. No doubt who owns the full-back spot.
75' Not entirely sure how Messi found Vidal so free with that pass. Aleix Vidal tried to take it around Adan and the keeper gets a leg to it before Real Betis put it out for a corner.
73' Sting very much gone out of this one. Barcelona are very comfortable and Real Betis can't invent any chances. Only a matter of time, it seems, before Barca get their third despite not looking entirely sharp themselves.
72' Francis Guerrero comes on for Nahuel.
71' Messi fires a free just slightly over the bar.
70' Aleix Vidal is coming on in place of Gerard Deulofeu.
70' And now Joaquin fouls Deulofeu.

68' Former Man City midfielder Javi Garcia is coming on for Juanjo Narvaez.
66' Some nice interplay by Barcelona and it ends with Semedo seeing a cross blocked up into the air, which Adan gladly accepts.
65' Deulofeu goes down under a tackle from Barragan but ref says it's a goal-kick. Great tackle.
64' Camarasa tries to find Narvaez but can't and Barcelonaback on the ball.
63' Nahuel turns Sergi Roberto upside down and gets himself a booking.
62' Barragan with the ball through to Nahuel but the ball but it trickles over the line before he can reach it.
61' Joaquin fouled by Busquets.
60' Messi strikes the post after receiving a pass from Busquets. It took a deflection as Barcelona win a corner.
58' Aleix Vidal warming up for Barcelona.
57' Ball in behind by Semedo is too heavy for Deulofeu as it rolls out for a goal-kick.
54' Narvaez is fouled by Jordi Alba and the left-back might be on thinner ice now after the yellow just a couple of minute's ago.
51' Jordi Alba with a yellow card for a foul on Nahuel. He's not happy but I'd say when he looks back at it, he might understand.
48' Deulofeu wins a corner for Barcelona as Tosca blocks a wannabe cross.
47' Mascherano fouls Sergio Leon as he grabs his ankle.
46' We are back underway!
When Barcelona are in need, it's not Messi they need, it's Sergi Roberto.
Barcelona enjpying 63% of the possession so far. They've had six shots and Real Betis have had none.

44' Semedo impressing at right-back.
42' Sergi Roberto with a high foot and Real Betis have a free out.
41' And just like that, Barcelona have a two-goal lead and can breathe a little but. Real Betis have thrown this one away.
39' Straight up the other end and Deulofeu grabs a yard on the left and he squares to Sergi Roberto who buries it! No chance for Adan as his defenders were ball-watching.
38' Sergio Leon with the chance of a lifetime as he is one on one with Ter Stegen but Mascherano gets back and takes it off his toe.
36' GOAL! Deulofeu drives a low and hard cross into the box. It takes a deflection and goes into the bottom corner of Adan's net.
35' Messi again. He rattles the upright this time. Adan reaching and nowhere near it.
34' Deulofeu finds himself free down the right and drives a shot towards the centre. It's beaten away by Adan but there are no Barcelona players to pick up the pieces. Busquets is fouled by Narvaez outide the box. Messi licking his lips...
32' Betis are probing a little bit more now. Narvaez with a mistimed pass and they lose out again. Barcelona struggling to get possession now.
30' Betis getting closer. Sergio Leon flicks one up into the air for Nahuel. Barcelona get back in time to foil their plans of a shot at goal.
29' Up the other end and Barcelona have a shot with Sergi Roberto. That's blocked too. Corner to the home side.
28' Sergio Leon breaks free and has Umtiti for company. He cuts inside and then turns back again before shooting and having his shot blocked.
26' Narvaez bundled over by Umtiti. Needless foul as Barcelona seemed to have Betis contained.
25' Chance! If anything happens, it will be that man, Messi, who makes it happen. He plays a couple of passes between himself and Busquets and then strikes just centimetres wide of Adan's goal.
24' Barcelona continue to build but no chances yet and so often very blunt up front.
23' Audible groans around the Camp Nou as Deulofeu coughs up possession with a poor touch. Busquets then fouls Narvaez and Real Betis have a break.

18' Narvaez buys himself a free as he baits Sergi Roberto into the foul to relieve some pressure.
17' Deulofeu sees a shot blocked and blocked. Joaquin under pressure has a dive in his own box and ref, rightly, doesn't give the free. Messi sees a shot blocked from the continuation of that.
16' Alcacer caught out for an offside.
15' Camarasa plays it out wide to Barragan and he keeps it going frther wide and forward to Nahuel but his cross is off target.

7' Mascherano fouls Sergio Leon as Real Betis look to break.

Barca players to wear Barcelona on the back of their jerseys tonight in memory of the deceased during the terror attacks during the week.

TEAM NEWS!
A reminded that Barcelona will be without Luis Suárez tonight. The Uruguayan picked up a knee injury in the second leg of the Spanish Super Cup, and will be absent for a month. Paco Alcácer is expected to take his place in attack.
It will be an interesting tactical match up at Camp Nou. Real Betis boss Quique Setién likes his teams to dominate possession and be expressive. With Javi García, Camarasa, and Fabián in midfield, Betis will seek to dictate phases of play, rather than just respond to Barça on the counter attack.
Javi García, Betis' new signing from Zenit Saint Petersburg, will wear the number 3 shirt. He's a defensive midfielder. Sacrilege.
