Now then. Lionel Messi goes to ground around 30 yards from goal and Barcelona have a free-kick.

Remember Messi's second against Liverpool in the 2018-19 Champions League? This one is in a similar position...

Pedri replaces Sergio Busquets - an attacking move from the hosts.

Good run from Gomez as the visitors enjoy a rare foray forward, but the Levante frontman gets crowded out.

Ronald Koeman is about to make his first change...

Lionel Messi skips past one or two defenders inside the area before poking the ball into Antoine Griezmann's path, but the Frenchman is dispossessed by the visiting defence.

Levante - unbeaten in their last six league matches - are proving a tough nut to crack.

That wasn't too far away.

Philippe Coutinho hasn't had his shooting boots on tonight.

The Brazilian finds a pocket of space inside the area but skies his effort high over the crossbar.

Better from Barca, who combine well down the left but Lionel Messi's shot is blocked by a Levante defender.

Plenty of neat and tidy play in and around the Levante penalty area, but the hosts fail to engineer a shooting opportunity.

No changes from either side at the interval.

Sergino Dest does well to beat his marker down the right and send in a low cross, but Aitor Fernandez is out to claim the loose ball.

Off we go again!

Barca are first to emerge for the second half, swiftly followed by the visitors.

What will Ronald Koeman make of his team's performance so far?

A reminder that Barcelona have won all 14 of their home La Liga games against Levante, scoring 48 goals in the process.

They've also netted nine goals in their last two league games at Camp Nou.

Nope, that's your lot.

No stoppage time played at the end of an entertaining first half. Plenty of chances, but no goals... yet.

Time for one more chance before the interval?

The Levante midfielder is back on his feet quickly but is still clutching his left arm.

What an effort by Jordi Alba! The defender strikes Sergio Postigo's attempted clearance on the volley from the edge of the box, but Aitor Fernandez tips the full-back's shot over the crossbar.

He struck that so, so sweetly.
