The match Man United vs Arsenal was over. The result was a draw, Man United 1 vs 1 Arsenal. Although Arsenal has no pure striker, they still dominated the match. They almost made 70% ball possession, they made 17 shots. Meanwhile Man United only made 10 shots. However, it was not a very bad result for Arsenal although it makes Arsenal point is getting far from Liverpool point. Sure, Liverpool point is 70, Arsenal point is 55. It is simply no way for Arsenal to catch Liverpool. 
And through this, Arsenal have gradually made the road to the title of champion easier for Liverpool.
When Arsenal have no choice but to achieve class victories, they have drawn matches which have further increased their points gap with Liverpool and it has now increased to 15 points.
Now Arsenal team has no choice but to win the next five matches and pray for Liverpool to lose the next five matches. And I think that is impossible because even if Liverpool loses one or two matches by chance, they will not lose five matches in a row. Although Liverpool has lost only one match this season
