Liverpool lost a great opportunity, they are now in second place. Their championship chances have decreased because their fixtures are very difficult. There were very few places that saw them as first favorites anyway, Manchester City and Arsenal are much more confident. Liverpool will most likely finish the season third. I calculated that they would get 15 of the remaining 21 points, and that is at best. They have now lost their psychological superiority.
Liverpool failed to use all the chances that they had in the first half to score more goals, and they thought that is how the match will be only to their favor. They forget that in football the opportunities that you create for yourself and how well you were able to convert it to a goal is what matters the most. This gave Manchester united the chance in the second half to panic Liverpool and scores 2 goals.
Liverpool was lucky that a penalty was given to them, if not they would have lost all three points today. Liverpool managed to draw the match in order for them to share points with United. It is a tough season where only 10 goals and one point makes the difference on the three clubs topping the table. Whoever loses any match will make his chances of winning the trophy slimmer. Let the competition begins with the rest 7 matches.
There is no way Liverpool was going to win Manchester United at old Trafford after what happened to Manchester United during the week when they played Chelsea, the best result Liverpool could for Liverpool would have been a draw which they achieved it, after a dominant first half from Liverpool which ended 1:0 in favour of Liverpool Manchester United git their tactics right in the first 20 mind of the second half allowing Liverpool do the playing and hitting them on a counter,
Dropping points at this time for teams in contention for the title and teams in contention for European spots will prove costly at the end of the season, at least with the draw it still keeps them on second position with an inferior goal difference to arsenal with more than 5 games to play.
