Barcelona will play Atletico Madrid on Wednesday in the Champions League quarter final second leg. The first game at the Nou Camp ended 1-1, and now Barca have to travel to Madrid to face a tough game which they must overcome to proceed to the semi finals.

Today's game starts at 7.45 p.m. BST (2.45 p.m. ET) and can be watched online through live stream – free for subscribers – via the link provided below.

Atletico Madrid are the surprise leaders in the Spanish La Liga at the moment with just half a dozen games to go. They have captured the imagination of many neutrals and many are cheering them on to overturn both Barcelona and Real Madrid to claim the title – which would be the first time another team apart from the big two in Spain have won the title for a decade.

Barcelona know how good this Atletico team is and they will be weary coming into this away tie at 1-1.

Atletico had held a 1-0 lead in the first leg but Barcelona gave themselves a good chance by getting the equalizer, and they will now be focused on trying to get an early goal to take the lead, but especially to wipe out the away goal that Atletico scored in the first leg.

If the game ends 0-0 tonight, then it will be Atletico and not Barca that progress to the semi finals.

Barcelona will of course be looking to Lionel Messi for inspiration and an impact up front. If Atletico cannot control and contain him then they could face a tough game today.
