I don't know what the result will be, but as we are talking on the forum right now, I think the Manchester United-Barcelona match is being talked about all over the world. There was no interest in the European league as before, but the teams eliminated from UCL definitely made this place very exciting. Since Manchester United could not finish the group as the leader, they had to stay in these matchups. I think Barcelona is better and will pass the elimination.
Indeed, no one knows who will win that match. Discussions about the big match between Barcelona and Manchester United will of course be very interesting because basically both teams have a large fan base.
Even though this match will actually be played in mid-February, I have found that some betting sites tend to think that Barcelona is the favorite. On the form of his team Xavi and Barcelona deserve it, but I think there will be some changes in the future when the league starts.
