Juventus came back from two goals down to draw 2-2 againstBayern Munich in the first leg of their Champions League last 16 match on Tuesday.

Thomas Mueller and Arjen Robben scored either side of halftime for Bayern but Paulo Dybala reduced the deficit with his first Champions League goal shortly after the hour.

That seemed to inspire Juventus, which almost leveled shortly afterward, before substitute Stefano Sturaro grabbed the equalizer 14 minutes from time.

"We need to build on the second half in which the lads played brilliantly," Juventus coach Massimiliano Allegri said. "We need to improve from the first half but don't forget that Bayern is a great team, you just need to see how they pass the ball. And we didn't give them too many chances.

"They dropped a bit in the second half and we got braver. That's what we need. In Europe you need a lot more courage because what we are doing in the league is not enough."

Bayern goalkeeper Manuel Neuer was mainly a spectator in the first period, when he was often the only player in his half, cutting a lonely figure as far up the pitch as around the center circle.

"It was a good Champions League match between two great teams," said Bayerncoach Pep Guardiola. "We had a really great performance. We can't forget who we played against: last year's finalists, champions of Italy the past four years, just won 15 games in a row ... I'm a bit disappointed by how we played not to have won but that's football."

Barcelona won 2-0 at Arsenal in Tuesday's other match.

There were some familiar faces for Juventus and Bayern Munich.

Arturo Vidal joined Bayern from Juventus last summer and his name was applauded by the Bianconeri fans when the teams were read out. Another former Juventus player, Kingsley Coman, was on the bench.

Former Bayern forward Mario Mandzukic returned for Juventus, following a month out injured, and had a couple of early chances against his old team, but Neuer made a comfortable save in the opening minute and Mandzukic fired wide of the right upright following a great cross from Dybala.

Otherwise it was all Bayern.

Vidal was the first player to test the goalkeeper and Gianluigi Buffon did well to palm away a volley from his former teammate in the fourth minute.

Bayern should have taken the lead in the 14th when Leonardo Bonucci allowed Robert Lewandowski through and he pulled back for Mueller, who seemed certain to score from three yards out but Bonucci atoned for his error by running in to clear away the German's tame shot.

Mueller was not going to miss twice, however, and the World Cup winner put Bayernahead on the stroke of halftime. Robben's cross was put back in by Douglas Costa and Andrea Barzagli's attempted clearance was straight at Mueller, who slotted into the bottom right corner.

Juventus seemed content to sit back in the opening period but appeared more determined after the break.

But it went from bad to worse 10 minutes into the second half when Lewandowski picked out Robben and he cut inside the penalty area before curling into the far side of the net to finish off a counterattack.

Bayern appeared headed for a fourth successive win against Juventus but the hosts kept attacking and got one back in the 63rd when Mandzukic took advantage of Joshua Kimmich's poor clearance to send Dybala clear and the Argentina slotted past Neuer.

Juventus almost leveled immediately after but Juan Cuadrado's effort was parried by Neuer and Paul Pogba curled narrowly over the bar.

The equalizer came from an unlikely source as Alvaro Morata nodded on Mandzukic's pass to Sturaro, who fired into the roof of the net.

Barcelona's strike force proved too hot for Arsenal to handle as Lionel Messi scored both goals for the titleholders in a convincing 2-0 victory in the last 16 of the Champions League on Tuesday.

Messi provided a clinical finish to a breakaway move that featured strike partners Luis Suarez and Neymar in the 71st minute, and then scored an 83rd minute penalty to seal a tense first-leg match at Emirates Stadium.

The five-time world player of the year decided a game that Barcelona had dominated, even without taking all the chances that came the way of its prolific forward line.

Arsenal created opportunities in both halves, but was mainly engaged in a damage limitation exercise against a side that the club's own manager Arsene Wenger described before the game as "super favorites."

It's a tag that Barcelona certainly has now.

With two away goals and home advantage to come, Barcelona will be confident of reaching the quarterfinals for the ninth consecutive season after the second leg on March 16 at the Nou Camp.

"I liked everything about Barcelona today, everything from the very beginning," the Catalan club's coach Luis Enrique said.

"My players individually performed perfectly and I think we are deserved winners of this game. The score is very good, but nothing is decided yet. We will have to play really well in front of our crowd in order to be in the next round."

Barcelona had beaten Arsenal in both their previous meetings in the knockout stages, in 2010 and 2011, along with the 2006 final in Paris. Its second-half performance on Tuesday, which combined possession with dangerous counterattacks, was a potent reminder of that track record - and another source of frustration for Wenger.

"They are better than us, and I believe everybody knows that. But I think we could have won the game tonight if we had kept the discipline until the end," said the Frenchman. "Barcelona masters all aspects of the game, and as soon as you're in a bad position with one or two players you can get punished."

Wenger accepted that his side's chance of advancing hung by a thread, but he said he does not plan to field a weakened side in Spain.

"Barcelona is through at 95 percent certainly, but we want to go there and play," he said. "We are Arsenal football club."

Despite the disappointing ending, his side made a bright enough start and carved out a half-chance after only eight minutes. A clever backheel by Aron Ramsey found Mesut Ozil, but the return pass wasn't good enough for the Wales midfielder to get a clean shot away.

Arsenal was clearly looking to move the ball forward quickly on the break, as Barcelona gradually took control of the play - though the visitors were initially showing a lot more patience than real attacking threat.

Instead, the hosts came close to breaking the deadlock when Hector Bellerin's blocked shot ran free in the area for Alex Oxlade-Chamberlain, whose low shot from close range drew a smart save by Marc-Andre ter Stegen.

Despite all its share of the ball, Barcelona's first real chance came midway through the half with a free kick on the edge of the area that Messi ploughed into the Arsenalwall.

The holders were gradually ratcheting up the pressure, though, and should have opened the scoring on the stroke of halftime. Dani Alves lofted in a clever ball from the right side of the area but Suarez could only flash a glancing header across the face of the goal.

It was a scoreline that seemed to satisfy Wenger, who kept his team on the defensive for the second half.

Yet Barcelona ripped through Arsenal's defense barely three minutes after the re-start with a superb pass for Neymar, whose shot was blocked in a one-on-one with Petr Cech.

Arsenal replied with a header from Olivier Giroud from a Nacho Monreal cross that Ter Stegen did well to block as the pace and tempo of the game ticked up.

Messi had a shot in the area charged down, Suarez sent an inviting low pass across the face of the goal and it seemed to be only a matter of time before Barcelona scored.

The goal duly came when Suarez released Neymar down the left and Messi had time and space to beat Cech.

"We are extremely guilty, we have no excuse for that goal." Wenger said.

Suarez then somehow managed to hit the post from point blank range after a pass from Messi from another breakaway.

However, Messi made such no mistake from the spot after being tripped by Mathieu Flamini, sending Cech the wrong way with the spot kick. And only a fine save at the end by the Arsenal goalkeeper prevented Neymar from adding a third with a header as Barcelona staked its claim to a place in the quarterfinals.
