It's quite impressive for Manchester United to be able to prevent Liverpool from getting three points in this match, because Manchester United managed to hold Liverpool to a draw, which basically that Liverpool really needed full points in this moment.
Liverpool before the match, were considered as stronger and could win this match easily but as a match between two big clubs, Manchester United even don't have good form recently, are able to constrain Liverpool. It is not an easy match for both and a draw is like a failure for Liverpool in their title race.
With results like this,Arsenal and Liverpool now really have the same points with the same number of matches and yes, it would be interesting if the winner of the trophy was only determined or only had a difference in the number of goals.But indeed, there are still many matches to be played until the season ends, so Arsenal, Liverpool and Manchester City will really continue to compete to finish at the top because now their points difference is only one point with Manchester City.
Arsenal and Manchester City still have matches with big clubs in top six and chances to win a title is opened for all three competitors. One match can change positions in top three a lot like this match can be used as an example. Anyway Manchester City still have less chance in this race by temporary points and positions of all three clubs.
