Arsenal is the only team in the Europa league that I am very sure they can always perform very well always and they have the chance of winning the league because they are much consistent than every other team in the europa league. I can't really give account of Barcelona in the europa league.
as long as arsenal hasn't played against barcelona, I don't agree with you that arsenal is the best team in european league
Juventus also still have the chance to become the favorite team to win because we have seen for ourselves how Allegri managed to build this team from its slump at the start of the Serie A season
it seems that the European league competition will be fierce and the four big teams (MU, Barcelona, Arsenal and Juventus) have an almost even chance of being able to win the uel this season
