Previously I had expected Manchester United to have difficulties in the Europa League after their inconsistent performance last season, they were only able to finish in 8th position in the EPL standings and qualified for the EUL through a special route after winning the FA Cup. The draws against Twente and Porto strengthen the assumption that they will have great difficulty in qualifying for the next round, even if they can do it, it will have to be through the play-offs. There are still six matches left to be played, the potential to collect points is still wide open but not a guarantee because their performance has not shown any signs of improvement.
At this point I wouldn't be surprised if they get a draw or a defeat. Manchester United's form is really bad and it wouldn't be surprising if they don't make it to the next round. It seems like Manchester United have lost their prestige as a top European team. A few decades ago everyone would have been surprised if a team like Twente or Porto got a draw against United. But now a draw seems normal. Porto and some other European league teams are on the same level as Manchester United at the moment.
Talking about their chances of making it to the next round I think United still have a chance to make it but I think they will take the play-offs route. I think the best result they can get is to make it to the round of 16.
