Liverpool's failure in the UCL seems to be a bit advantageous. This condition can make Liverpool fully concentrate on the EPL. Currently, Liverpool has a difference of 12 points with Arsenal. Although Arsenal still has a chance to continue in the UCL, it will make Arsenal a little more tired. So Liverpool should be the best candidate for the EPL champion this season. As for Aston Villa, they seem unable to compete well in the EPL. They are out of the top 5 warnings right now.
Liverpool getting out of the Champions League may be advantageous to them, but they shouldn't have left so quick when they have already given much effort from the beginning only to fall out along the line. Besides they were still topping the Premier League table before they fell out of the Champions League games but anyways, since they will be concentrating more in their Premier League games, it will give them an edge to draw closer to the title glory and it is becoming a reality for them already due to the point gap they are topping with. Arsenal is not to be trusted in the Champions League because they almost put in same efforts as Liverpool did, except they will prove that they are prepared this time around if not it has always been same story for them whenever they appear in the Champions League so until they make improvements, they can't be hoped on to do anything in the Champions League games, Moreover there are still teams that are stronger than Arsenal so it will be difficult for them to scale through. Aston Villa have been so loose this season in the Premier League but since they have also given some good display in the Champions League and got to the level they are now, they have also tried their best and even if they don't advance further, they have at least gotten the Champions League experience. There is a strong challenge in the 5th position in the EPL which means that Aston Villa may not have the privilege to reach the 5th position and qualify for the Champions League next season.
