We will receive the first answer to this question on April 10th. If Liverpool win they will be huge favorites for the title. I also think that Liverpool are worthy of the title first of all because they had a great time for a significant part of the season without their main players who participated in the Africa Cup until the very final. I think Liverpool are going through tougher challenges than City this season and more successfully, so it would be fair for them to win the title.
Liverpool are behind Manchester City with small difference but they have more advantage than Manchester City. City will pay more attention, concentration and resources for Champions League. They are obsessed with Champions League and will spend most of their resources there. Liverpool in contrast will still have a successful season if they can get a trophy in either Premier League or Champions League.
With Manchester City, they only see a successful one if they can win Champions League. Pep wants his first trophy there after leaving Barcelona too.
I don't think that City are so fed up with EPL titles that they are ready to put the Champions League higher in their priorities. Maybe if they had a guaranteed choice between these two titles, they would choose the Champions League, but there is no such choice, and even reaching the final, you can lose everything. In terms of reliability, the EPL looks much better, especially when your team is in the lead, albeit by a small margin.
