- Suspended Neymar out for Barcelona
- Barca six points behind leaders Real Madrid
- Osasuna bottom of La Liga
- Suarez set to sign new contract; Neymar suspended
Routine win for Barcelona. Two goals for Lionel Messi, in addition to Luis Suarez's opener, moves the Catalans back within three points of leaders Real Madrid.
Brilliant. Lionel Messi would find space inside a matchbox. The Barcelona star has a tiny piece of grass to work with inside the Osasuna box, a couple of shimmies and feints creating the room to drill in from a central position.
Three minutes of added time. Time for one more?
Lionel Messi isn't ready to go home yet. He dances forward from deep, skipping past a couple of would-be challengers before his shot is blocked by a last-ditch tackle.
Barcelona almost add a third. Jordi Alba races into space on the left flank, squaring to Lionel Messi. He flicks goalwards but can't beat Osasuna keeper Nauzet.
If goals were dished out on the basis of the vocal support, then Osasuna would have bagged a couple. The home fans still cheering their team on. Come on Barca, be generous...
We have not seen much of Osasuna left winger Alex Berenguer today, but now he pops up. He bursts past Sergi Roberto before cheekily trying to chip Marc-Andre ter Stegen from an acute angle. Maybe it was a cross. Whatever... the Barca keeper tips over his bar.
Denis Suarez leads the Barca break, but Osasuna get numbers back to crowd him out. Danger averted.
Osasuna are still plugging away. Miguel de las Cuevas steams into the Barca box on the right, looks up to see who's there. A couple of red shirts wait, but he takes the wrong option with the pullback. Sergio Busquets clears and Barca counter...
Hang on, Osasuna aren't throwing the towel in just yet. Sergio Leon, their brightest spark, has a pop from distance. Marc-Andre ter Stegen wakes from his slumber to save.
This is like a training exercise. All Barcelona possession, all Osasuna defending.
Osasuna must have known Lionel Messi would score today. He always scores against them. That's his 16th goal in his last nine league appearances against Los Rojillos.
Game. Set. Match.
Barcelona score the second goal they deserve - and needed. Another wonderful team move leaves red shirts scattered across the pitch, Lionel Messi nipping into space to clip over home keeper Nauzet Perez. He can only stand and watch the ball sail over his head and drop into the far corner.
Can you imagine if Barcelona blow this lead now? Osasuna haven't had a sniff really, but Barca need another to give themselves breathing space.
Oriol Riera's afternoon is over. Osasuna's ex-Wigan forward won't be adding Barcelona to Real Madrid in the clubs he has scored against this season.
Barcelona don't look in a massive hurry to kill off Osasuna. Perhaps they should be. Lionel Messi has a sniff, only to see home keeper Nauzet Perez deny him again.
Now Barcelona decide to make a switch. The almost anonymous Arda Turan is the player hooked, Denis Suarez coming on.
Time for an Osasuna change. But it is not a positive one. Off goes centre-back Oier, with another defensive-minded player - Tano Bonnín - coming on.
