It have arrived the decisive chalenges in the Champions League. The age of those games wich have realy importance and are always a great football show. In my view, the game of the qualifying stge are, sometimes, boring and bureaucratic, mainly when those traditional clubs face teams without great players. 

It's hard to guess the result of all games, but I have some opinions about these games.

• Celtic FC x Barcelona: The catalan team gets to win the Scottish defensive sistem. Messi e Bojan must call the atection on the match and it's a great oportunity to Ronaldinho show that football that he played for some years in this competition. 
• Lyon x Manchester United: I'm used to see Lyon arrives untill a decisive stage and fall against a european giant. Besides, ManUtd has a great team, one the best of these last times. Ronaldo and Tevez are in a so fabulous stage. United pass without problems.
• Schalke 04 x Porto: Each one wins in their homes and Porto FC gets the qualifying after penalties.
• Liverpool x Internazionale: I realy don'n trust in this italian team. It's already two years falling against midle teams. This time, I think the italians get neither arrive untill thesse midle teams. Liverpool wins with a double 1-0, but without to be threaten.
• Roma x Real Madrid: The best game of this stage. The two teams has big players and Roma promises to face Real Madrid without to be afraid. I trust in this italian team and in the couple Mancini and Totti. The italians still have Juan, the best defender of the world. Besides, Madrid has a sad past playing against italians team. But, a dispite of that, I think Madrid reachs the next stage.
• Olympiacos x Chelsea: The greeks have alredy arrived so far. And Chelsea will count with africans players again.
• Fenerbahçe x Sevilla: Two midle teams who have been improving their performances. I bet in Sevilla, but I'm not sure about that. I would not be surprised if the Alex and David's teams gets to give this gift to coach Zico.
• Arsenal x Milan: After what happened to Ronaldo, my great idol in the football, Milan deserves to pass. I will keep my fingers crossed by the Ronie, Pato and Kaka's team. However, The English team is dangerous, mainly with Fabregas and Adebayor in a inspired day.
