Manchester United is surely struggling into English Premier League, so they have another good chance for going into Champions League which is won of Europa Cup win even it's also not easy for any team as now competition is tough, and many quality teams are doing good job but their improvement in performance a having four wins in row surely giving good impression now they are capable for having good chance with Arsenal and Ajax which is also going to fight for this as they are currently at the top of Dutch League, so they can do good here in this competition as well.
Here now we need good adjustment from coach because this is also very important if you want to have positive results then you need to work on few things which create good chances and right players able to have positive results from these changes hopefully things could be good.
They are not really "that" bad, they are missing one game and only 3 points behind. Which means if they win the game, they may become 4th which is UCL levels. I mean isn't that what the aim was at the start of the season? To be a top 4 team? If they won against Villa they would not only be fourth but also have one more game to play as well, so that would be awesome but even with this situation they are still doing fine.
Lets not let the start of the season cloud our judgement of how they are right now, they may have started the season terribly but they are doing much better right now. This is why I am guessing that they will have a better run at things after the world cup break.
