Barcelona vs Atletico Madrid Live Stream Free: Watch Online Champions League Football (Preview, Start Time)

Barcelona and Atletico Madrid will compete in an all-Spanish match up in the Champions League quarterfinals on Tuesday night. Barcelona have by far the higher pedigree in Europe, but this season Atletico have shocked everyone with their excellent and consistent form, and they are currently the team at the top of La Liga.

The game is scheduled to start at 2.45 p.m. ET and can be watched online through free live stream (details below).

Barcelona will be hoping to teach Atletico that good form domestically does not always translate to the same on the European stage. In Europe Barcelona have been kings, even though right now Atletico are top of La Liga.

Also even though this is a European tie, it will be hard for Barcelona to impose their European dominance over their Spanish rivals, and this could easily feel like a domestic affair.

That's exactly how Atletico will want it to feel. They have shocked everyone with their form this season, and even though many believed they would fall away at some point, they have maintained their form even better than Barcelona and Real Madrid – who have both suffered wobbles at certain times this season – and that has allowed them to command top spot in Spain's premier league.

Martino has said ahead of the game that he for one is not surprised a how well Atletico have done this season – even though the last time they won a league title was way back in 1996.

"They have sustained a great level all season and last season too," he added. "They are in the final stages fighting for two competitions and it is clear how strong they are."

This match up should be a fantastic spectacle, and even after this two-legged affair is done, the two teams will also face each other in the final game of the season in La Liga, which many are touting could be a title decider.
