Bayern beats Barca ??

I heard this morning that bayern munich beat Barcelona 4-0?
I read the message twice. I didn’t believe it at all.
All people are going mad over it but does one defeat really mean Barcelona is over? Messi is no longer a good player? :)
I don’t think so. You never know what happens in the return leg.
May be a miracle is awaiting everyone. We all know Barcelona is capable. Xavi has admitted It’s next to impossible but still hope is there.
My concern still remains the same will Arsenal finish third in EPL?
With Arsenal I remember, it was the same bayern team which was beaten by Arsenal 2-0 few weeks back.
I am sounding like a typical arsenal fan now. Lolz.
