Do you really think this is news? Everyone knows about Arsenal. However, they are clearly progressing and financially successful, and apparently the management is happy with this state of affairs. If you put aside the meme-ness of their failures, on average they are good.
As for the Inter - Barcelona pair, Barcelona was overrated so many were surprised by the result of the first game. I wrote before the game that this was an equal pair, and Inter never had problems knocking Barcelona out of the playoffs.
C'mon man don't say Barcelona was overrated man, I mean this Barcelona have proven they can actually play and even with this game ending a tie at Barcelona home am still sure Barca can stir up something when they go to Italy. Although Inter Milan is no small team because they get to remove the likes of Bayern Munich and other tough opponent so no what transpires as the final result it will be worth it.
Proven when? When have they beaten crisis-ridden Real Madrid? Even Arsenal can do it

At the moment, Barcelona have not shown anything that could be rated as 1.47 against Inter. It is an even match.
I see that even after the first game, where Barcelona miraculously escaped, the odds are extremely crooked:
3.05 - 3.95 - 2.16
I hope the bookmakers are just following the crowd (money flow) and not crazy enough to give such odds seriously.
