Barcelona has been playing a 3-4-3 formation over the past few games.
What you think about that? It gives them an extra man in midfield to dominate position and create more opportunities, but it leaves them exposed in the back.
If they think they can use this against top teams in Europe, I think they'll fail. I think this is a good tactic for home games against most teams, but it's not something to use against good teams who can hit you on the counter or those who can play close to an even game with you.
Anyways, I think it's risky. It's cool to see the inovation, but this could be their undoing. I don't think anyone can beat Barcelona over the next 3 years, but they can certainly beat themselves.
