Yes, the target is unrealistic to fight at the top standing. Many observed say if MU could be degradation if they don't rebuild their performance can be better. Amorim have the trouble to build the team like he expect because the squad have problem with desire with others. There are some players who want to leave, and some of them still want to stay on MU, but the official want let them go. This is important problem which MU will face because at other side, many club out there won't buy the MU player. The MU player is have the problem with peforma, they are fits, but because they often lose, so if they joined to new club, their poor performance will affect to others players.
Manchester United have good players but they are not good enough to compete for top four or the league title, but are not too worse to fall to relegation zone. Top 6 is possible for Manchester United if they can improve player mentality and create motivation for their players to fight more serioulsy and perform better together.
A positive result with Liverpool, a draw when most people thought of a defeat or even a big defeat for Manchester United, can help them to move forwards in next matches with positive momentum. If they can maintain it, their confidence will be back and performances will be improved in future. This season is wasted for them, but if they can join higher position range, and be eligible for either UEFA Europa League or Conference League next season, it's a small success for them. At least they will have extra income from playing in either Europa League or Conference League, and it is also helpful for them to attract star players in summer transfer market.
