Five reasons to believe in a miracle against PSG
The hammering of Celta Vigo, as Luis Enrique said, was "possibly the best guide" to begin to believe in a comeback against PSG.
Neymar reinvented his form
The Brazilian has been the most in-form player on the team for several weeks. For a number of games he has been playing with spectacular confidence. The result, a player who shines one-on-one, constantly involved in attacks, but also contributing in defence. But there's more: now he's started scoring goals. The finish against Celta was outrageous - as was his free-kick against Sporting Gijon.
Busquets back to his best
Few players can be used to measure Barca's form as much as Busquets. If he's in form, Barça usually play well. If he's not at his top level, the team can have problems on a structural level. Against Celta he was at his best, as was Ivan Rakitic and Barca appreciated it, as it always allows for more from the trident.
There are few doubts that Barca will play 3-4-3 against PSG. Since the win at the Vicente Calderon, Luis Enrique has been tweaking the system to get the best from it. But until the game against Celta, we hadn't seen it at its very best. One doubt is who will play on the right of midfield. Rakitic and Sergi Roberto have options to be in the team, while a defence of Umtiti, Pique and Mascherano is possible. Alba could be the player sacrififced. Iniesta will return to the side in midield.
Leo Messi is pumped up
Something has been stirring in the Argentine for a few weeks. You only have to look at some of his recent goal celebrations. Barca need a small miracle against PSG which is where Messi, the King, comes into his own. Against Celta he was superb and the French side will know if he has one of those days on Wednesday, they will struggle at Camp Nou.
PSG are inconsistent
Unai Emery's side once again showed they have weaknesses as they struggled past Nancy this weekend. It's true that they were not at full strength, but, also, they looked fragile in areas and gave away a number of chances to a side in a relegation battle. PSG's performance in the first leg was way above what they usually produce in Ligue 1. On Wednesday they arrive with a huge advantage, but against a trident and a packed Camp Nou pushing for history to be made.
