It was already obvious before the match that Barcelona would lose it. And they did by a big score like 3-0. Barcelona's current condition is not good enough to beat teams like Bayern Munich in home or away matches for now. They must improve their game a lot to talk about that probability. They don't belong to the Champions League for now and they are already eliminated from it too.
Was nt obvious because Bayern only played Tolisso in MC who has barely played all year and poor on the ball/turn. Sule is also poor on ball so you could have used that to your advantage but fell off pressing due to Bayern overloading the AM area.
