It is possible to occupy 4th place because of the difference in points far next week Manchester will face Aston Villa and it must win because the next match will face Tottenham. I will be difficult for Manchester United to move up the table.
The top four have around 7 points difference with the #5. So, in order for United to get inside the top 4, then one of the teams must lose at least 3 times and at the same time, United keep winning their game.
That's a tough task, considering the current top 4 has consistent runs.
