37 min: Now Iwobi gets a chance, but the ball sits up for him and he skies it high and wide. The Gunners need to be taking these rare chances.

39 min: Sanchez has an effort! Great play from Ozil before a lovely cross from Bellerin. The Chilean can only head wide.

40 min: Nice one-two from Iwobi and Welbeck before Welbeck slices his short well wide. Mascherano just did enough to track back. All Arsenal this one at the moment..

43 min: Arsenal break forward, Sanchez finds Ozil, but Ozil's return pass is easily snuffed out. Doesn't look like the Gunners will be scoring before half-time.

44 min: Substitution by Arsenal: Flamini has been replaced by Coquelin. Such is the odd timing of this change Flamini must have been carrying an injury but he was of course, on a yellow card. Updates to follow.

HT: And that's the end of the first half! Too comfortable for Barcelona. The Gunners, who have had some opportunities, still need at least three goals in the second half, but on this form it's Barca in Friday's draw without having to go into second gear.

[16 March 2016 20:59 · James Orr]

55 min: Great save from Ospina, who dives low to palm away Messi's drive. The danger from Barca is always there.

[16 March 2016 21:01 · James Orr]

57 min: Welbeck with a chance for Arsenal! He's looks to have taken the ball past Mascherano but the Argentine makes up for it with a heroic block. 

[16 March 2016 21:03 · James Orr]

58 min: Neymar now charges into the Arsenal box but Gabriel makes the tackle. End-to-end stuff at the moment.

[16 March 2016 21:06 · James Orr]

62 min: Iwobi finds Sanchez in the area but his shot is deflected over. Then Welbeck gets a header on the ball from the corner but it goes wide. So many chances from the Gunners, but they are just not taking them.
