TWO goals from Lionel Messi steered Barcelona to a convincing 2-0 victory over Arsenal in the last 16 of the Champions League on Tuesday.

Barca coach Luis Enrique joked this week that all he needed to do was shout “Abracadabra” for Messi, Neymar and Luis Suarez to deliver the kind of magic display that would bewilder the Gunners.

On this occasion, it was Messi who answered his coach’s call with a second-half brace as the Spanish champions survived a stern examination from Arsene Wenger’s side to escape the Emirates Stadium with a result likely to condemn the hosts to a sixth successive last-16 exit.

The leaders of La Liga, chasing a sixth European Cup triumph, are now unbeaten in 33 games in all competitions — a blistering streak that includes 14 wins from their last 15 games.

After being dazzled by Messi’s magic wand, it will take an act of astonishing escapology for Arsenal to go through in the return leg at the Camp Nou on March 16.

“I liked everything about us today from the very beginning,” Enrique said.

“I liked the way we scored and we had plenty of possession.

“Our opponent defended with every player in their own half but we still managed to hamper them.”

Wenger added: “Barcelona is a great team. The regret I had was we looked like we could dominate the game, then we give the goal away.

“Realistically it is very, very difficult, if not impossible (to make the quarterfinals).”

Aware that Arsenal’s refusal to curb their attacking instincts had left them fatally vulnerable in the Champions League knockout stages, Wenger set out to stifle Barca with a cautious game plan.

Nacho Monreal had clearly taken Wenger’s words to heart and he earned an early booking for chopping down Ivan Rakitic.

But there was more than just mindless muscle to Arsenal’s approach.

Aaron Ramsey sent Mesut Ozil clear down the left edge of the penalty area with an exquisite backheel and then raced onto the German’s return pass for a powerful shot that was blocked by the visitors.

Only a last-ditch block denied Hector Bellerin, with the rebound falling to Alex Oxlade-Chamberlain, whose scuffed close-range shot was straight at Barca goalkeeper Marc-Andre ter Stegen.

But with half-time looming, Barca, refusing to be hounded out of their stride, finally escaped Wenger’s tactical straitjacket.

An opening goal should have followed when Dani Alves met Sergio Busquets’ pass with a volleyed cross that Suarez headed wide with only Petr Cech to beat.

Completely anonymous in the first half, Neymar underlined Barca’s renewed sense of purpose immediately after the interval with a surging run past Bellerin onto Andres Iniesta’s astute pass.

The Brazilian should really have scored, but Cech came to Arsenal’s rescue as he raced off his line to save.

Olivier Giroud rose above the Barca defense to meet Ozil’s cross with a header that ter Stegen brilliantly clawed away.

But Enrique’s men were irrepressible and Suarez drilled narrowly wide of both Neymar and the far post.
