Barcelona must be careful with the improvements that happened with MU. Rashford will become the main key for united to be able to win against barcelona. Dembele might be a threat for MU but im sure that MU has good team for now. MU was able to beating manchester city. I think that the different between MU and barcelona are not too far right now. MU has capability to beat barcelona in the europa league. The play off to go to the last 16 of europa league become even harder.
Juventus is also starting to struggle with its performance in serie a. I think that MU and barcelona were equal at this moment consider from the result achieved by MU
Careful? You should have waited for the final result of the recently concluded Super Cup before making warnings for Barcelona, trust me. I know Manchester United has improved recently in their performance, winning teams that have been leading other leagues, but I think Barcelona would leverage their Champions League loss to win the Europa League on the bag, Xavi wants that, and looking at how smart Rashford is hot in Manchester United, Barcelona has Gavi as well, I can strongly say that Barcelona is upto this task to win the Europa League.
Juventus isn't too bad, Milan is just a point away, winning a single match will settle the points they need to be ahead. Nantes is the one who needs more warning considering their position on the table and the last matches they have played so far because it looks below average for someone who wants to win the Europa trophy.
