Lionel Messi unsuccessfully tries to juggle a long diag on his chest. He might be 'magic' but he is not quite Dynamo.

Barca are pinging the ball nicely around in midfield, just lacking a final ball at the moment. (Unless Osasuna provide them with one.)

Osasuna had to commission a new third kit specially for tonight's game as both of their other strips clashed with Barca's famous Blaugrana.

They look like a vintage Dutch side. Unfortunately none of their players look like Gullit or Van Basten.

The floodgates could open at any moment.

Lucas Digne has a go from distance, the French left-back's shot deflecting off a defender and going out for a corner. That comes to nothing.

A wonderful moment after Messi's opener as he jogs to the supporters behind the goal to celebrate. The Barca fans congregated there all hold up their shirts to the sky - mimicking Messi's celebration in the Bernabeu on Sunday.

"Messi, Messi, Messi!" Those inside the half-full Camp Nou find their voice to cheer their hero when he picks up the ball just outside the Osasuna box. However, he can't do much with it.

Ambitious. One of the Osasuna players has a pop from inside his own half... the ball barely reaches Marc-Andre ter Stegen. 

However... Three of Barca's four league defeats have occurred against teams in the lower half of the table, including their only home defeat, to Alaves back in September.

"We have had problems with teams near the bottom, which makes this a dangerous game for us," Luis Enrique said before kick-off.

Hmmm...

Basement club Osasuna have won only three games all season and could be relegated tonight.

If they lose to Barca and Leganes beat Las Palmas then the drop will be confirmed. Although in truth they haven't looked like staying up since before Christmas...

But they still haven't been troubled yet in the Camp Nou. Andre Gomes tries to thread a pass to Ivan Rakitic but it is overcooked and the ball dribbles out for a goal-kick.

You won't be surprised to hear Barcelona are hogging the ball. You may be surprised to hear Osasuna haven't been threatened yet.

This is a home banker on the coupon if I've seen one.

Barcelona have won nine of their past 10 games against Osasuna at Camp Nou, including the last five in a row.

The Catalans have only conceded one goal in the previous five home meetings, scoring just the 24 goals...

They include an 8-0 win in 2011-12 and a 7-0 thumping a couple of seasons later. Gulp...

Any in the Barcelona area? There are plenty of empty seats if you fancy making a quick dash. Tickets are about €60 a pop apparently...

The Camp Nou looks like it is in the middle of a fire drill.

Barcelona appear to have gone three at the back in this reshuffled line-up.

Two of the players who have not dazzled at the Camp Nou since their arrival - Arda Turan and Andre Gomes - try to link up in the opening few seconds.

Gomes miscontrols and the ball goes out.

Right then. Let's go.

The man of the moment kicks us off. That's Senor Messi.

Osasuna may be relieved to see only one of MSN lining up against them tonight. Unfortunately it is the 'M'.

Lionel Messi starts, Luis Suarez is given a breather on the bench and Neymar is out through suspension.

Barcelona XI: Ter Stegen, Sergio Roberto, Pique, Mascherano, Digne, Rakitic, D Suarez, Gomes, Arda, Messi, Alcacer.

Osasuna XI: Sirigu; Bunuel, Steven, Oier, Fuentes, Jaime; Tienza, De las Cuevas, Merida, Torres; Leon.

"Gracies Leo!" reads a huge banner flapping in the Catalan breeze as the two sets of players run out of the Camp Nou tunnel.

Underneath is the number 500. You don't need a GCSE in Catalan to work out what the message is...

All to play for...

Although Barca muscled their way back into the title race, the destination of La Liga is still in Real Madrid's hands. 

Madrid will win the title for the first time since 2012 if they win all of their six remaining matches - a feat which they did achieve in the first few months of the season.

Madrid are away from home four times out of six, with Barca - already knocked out of European competition - at the Nou Camp against lowly opponents on three occasions.

Atletico Madrid and Sevilla are well-placed to sew up the final Champions League spots with Villarreal eight points off the pace and hoping Real Sociedad and Athletic Bilbao do not improve over the run-in.
