Well, first leg between these two teams was a game in which we could see so clear the big difference in class. Celtic simply have scored 2 goals from their only 2 attempts while Barca have created so many chances and just have been unlucky. We all know the importance of an Champions League game and we all know that there are no games without motivation in this competition as is a proud for everybody who can at least to participate. I think Barca will play tonight with a lot of confidence as they already have won in first leg 2-3 and will play more for the spectators. I realy can't see them to try to make an surely match and thinking only on their qualification. Celtic will have to attack and this is another point as we all know how dangerous are Barcelona's players on countra-attack. They will play for fun tonight and will play without any pressure.
