What if we will only see the same united in UCL?
The club is still struggling in EPL. I expect nothing from manchester united this time. Being able to to go the play off stage will be big achievement for manchester united. Manchester united has been coming to the UCL without any preparations.
Playing in domestic league is always easier than playing in Europa League or Champions League. I don't expect Manchester United will be a different, in means of better team, in Champions League than what they shown in Premier League. They must improve their quality, then performances in Premier League to build up confidence for their players, before can make better performances in Champions League.
They have many problems in all areas especially defense that have yet been resolved. Those problems are barriers for Manchester United to succeed in Premier League and Champions League.
Teams from Serie A cannot be underestimated in the Champions League this season. The reason is that Inter Milan, Ac Milan, Napoli and Lazio could possibly make a bigger surprise like they did in the previous season. I'm sure Inter Milan is highly regarded by their opponents.
Chances for them to repeat success like the past season is slim. They are not actually too strong clubs compare to other big clubs in Champions League. So their success depends a lot on luckiness and I am doubtful that those clubs from Serie A will have luckiness in two consecutive seasons.
Apart from that, the rise of Bayern Munich will be a big threat to other teams because they are increasingly integrating their strengths. It's just that they really miss Manuel Neuer in their goalkeeper position. Harry Kane's presence will make the competition in the Champions League this season even more interesting.
Kane actually improves attacking power of Bayern Munich and he will be very helpful for them in Champions League. They are already one of strongest clubs in Champions League and with a striker who is ambitious to win big titles, first big ones in his career, Bayern Munich will become more dangerous. They also have some good attacking midfielders who can support Kane with key passes for him to find goals.
