Celtic won their first every away match in the Champions League on Matchday 2 versus Spartak Moscow and now face an even tougher challenge on Tuesday when they travel to the Nou Camp to take on Barcelona.
These two clubs will meet in back-to-back matches in European play, and for the Scottish club to make the knockout stage of the Champions League, they will probably have to take at least a point from one of these matches.
Surprisingly, Celtic's best chance to earn a positive result could be at the Nou Camp because Barcelona's defense has been surprisingly awful recently.
The first goal is going to be huge for Celtic because opening the scoring will boost their confidence tremendously and give them the energy needed to play 90 minutes of good football.
Barcelona will once again be led by star striker Lionel Messi, who is coming off a hat trick versus Deportivo La Coruña over the weekend.
The Spanish side has four players with at least one goal scored through two Champions League games this season and will need that same balance to defeat Celtic.
Alexis Sanchez, Cesc Fabregas and Cristian Tello are playing very well in European competition and will likely play a key role in this match too. Manager Tito Vilanova has so many quality attacking options to choose from on his bench if he needs a late goal.
Celtic are a good team that won't be intimidated by Barcelona, but it's hard to imagine them defeating the Spanish club when Messi and Co. are in form at the moment.
Barcelona has a perfect record in Champions League play this season, and it would be surprising if that was ruined on Tuesday.
