The both clubs Aston Villa would be fighting for fourth and fifth position at the end of the season if they can continue fighting the same way they have started. I will want to place Aston Villa ahead still because they have a manager who's experienced in the Premier League Competition and at the same time they have a good defense. Fatigue and too much games would be the challenges they'll be facing ahead. As per Chelsea, they are doing well right now but they don't have a solid defense system even though the coach is doing well. Arsenal and Manchester City are frontiers this season again. Let that sink in!
You just made mention of fatigue, i believe that's what gonna be a big challenge for Aston Villa this season since they are playing both in the champions league and the premiership and with their good start in the champions league i think they will still want to maintain same energy by working extra hard in their upcoming games so the players will definitely be so stressed unlike Chelsea that just have the premiership and few other England competitions to participate in. I think with how Chelsea have played so far they can still have the opportunity to at least make it within the 5th or 4th position depending on their level of consistency. Enzo Maresca needs to pay more attention to the defense as that is where they are having loopholes now. Manchester City, Liverpool and Arsenal are doing pretty fine so the title challenge will revolve around the three teams.
