Manchester united have the strength to defeat arsenal, arsenal are not looking tough watching from their previous game in Premier league, with this I'm not very sure if arsenal can be firm and not allowing a defeat from Manchester United. Manchester United are strong to compete with any big team .
My 2 favorite teams in England but Arsenal turn up to bigger games and Manchester United might have the better form now but it will still be a very difficult game for them. I would not count out Arsenal because they can bounce back at any time from their current form. I think it will be a close game and would probably finish as a draw or with 1 team just winning by 1 goal. I do not think any team would find it easy to beat the other.
If Manchester United can keep Casemiro fit I think they have the edge but without him then they fall apart. They have become very dependent on Casemiro who is a world class midfielder but I fear they have become too dependent on him and when he gets a injury or needs rest they will start dropping points again.
There are for sure some great names in the competition and it is also good that the favorites aren't eliminating each other just yet.
Freiburg is in good shape, but given that Juventus Turin has only one chance to save this season by winning this competition. They know that the Europa League is more important to them than ever. They are now 13 points behind in the Serie A, but if they can secure a spot in the Champions League for next season they can still look forward to a fresh start after this bad season.
