United should not be expected to do better this season. I mean in a "better" sense that they may not finish 15th, sure they can finish higher, but expecting them to be in top 4 or something? That is just a delusion and you are not going to see that. They didn't even do that many transfers, just two players so far, how could you expect them to do better?
I expect them to miss out on UEFA places once again, because neither Amorim showed any improvement after he took over, nor any players got any better. They need some more transfers for that to happen, if they do end up with 2-3 more players before the summer window closes, then yeah maybe they will get better, but the league is starting soon and they still didn't make a move yet.
