Barcelona vs Arsenal live stream: Watch Champions League 2016 soccer online

Barcelona and Arsenal will face off in the second leg of their Champions League Last 16 match up on Wednesday night, with the Gunners needing to travel to the Nou Camp and overturn a two goal deficit to progress to the quarter-finals. The game has a scheduled start time of 3.45 p.m. ET and can be watched online through live stream via the link below.

Barcelona managed to claim a 2-0 advantage when visiting the Emirates Stadium in London in the first leg, and that means Arsenal have been left with a mountain to climb if they are to progress and stay in this year's competition.

Barcelona will be massive favorites to move forward. Most pundits are of the thought that Arsenal will have to go out and attack Barcelona if they are to overturn the deficit, but that could play right into Barcelona's hands, and they will be at the ready with the likes of Lionel Messi, Luis Suarez and Neymar to pounce as the Gunners potentially leave themselves more exposed at the back.

Arsenal manager Arsene Wenger has said, "We don't have to calculate too much, we know we have to attack and score. The players are united to give a strong performance."

Many will see Arsenal as having been terribly unlucky in the first leg. For much of it they matched Barcelona, and could have been ahead. But with things still deadlocked at 0-0 with just 20 minutes to go, up stepped Lionel Messi to score two unanswered goals to put the Spanish giants in firm control of the tie.

Wenger did not feel his team did too much wrong in the first leg, saying: "Our approach was not bad in the first leg but we lost our balance and got caught."

Over the past few months, the Gunners season has seemingly imploded. They were recently knocked out of the FA Cup, and their campaign for the English Premier League title has hit a wall after a series of bad results, which leaves them lagging well behind surprise leaders Leicester City at the top.

Another season where a good position at the turn of the new year has nose-dived when the pressure has been on, has led to increased pressure on Wenger. Some Gunners fans have been calling for him to go, such is their dissatisfaction with the lack of progress at competing for the Champions League and Premier League trophies.

But Wenger has said, "I am even more motivated than the day I arrived. When you are a long time somewhere, people always question you. I don't question my dedication, it is 100%. We have gone through a disappointing spell and it is important to remain calm and strong."
