We should probably consider the situation to change, because I can't see 100% win rate from any of them, all three will lose points somewhere, the question will be which one will lose more than the other. Liverpool do not have any games left with them, but Arsenal will play City so one of those teams will lose points or maybe both of them could. That game will be a big decider.
Liverpool will face a much lighter match in Week 29 where they will face Brighton so the opportunity to secure the three points will be much easier. Man City and Arsenal will face each other this week and winning is important for both of them, because if they lose, their position will change in the third place in the standings. Arsenal will be under much greater pressure because they will visit Man City's headquarters in disadvantaged conditions.
Man City will not let Arsenal get full points at home, because if Arsenal wins the match Man City will be out of the competition, even though the points distance is not too far. Man City is much more favored to win the match because they will play with full strength and also at home.
