Aston Villa under Unay Emery has good progress because they can performing stable in Champion League and Premier League and you can see it based on their position on League standing because they can reach to top 5 in Premier league and in champion league Aston Villa performance is more impressive because they can gets 2 wins at the beginning of League phase and if talking about champion candidates of Premier league i think it's too early for them and Unay Emery as a manager also said the title is not the main target of Aston Villa because he has realize it is very hard to compete with big teams just like Arsenal, Manchester City and Liverpool

For Chelsea actually i was underestimate this team because this summer they have weird behaviour regarding player transfer and i doubt Enzo Maresca will be able to improved Chelsea performance because at the beginning of season Chelsea condition is messed up but clearly i was wrong about that because Chelsea gradually can find their shape again and Chelsea also is very productive with scores 16 goals total in Premier league and before this season begin the owner of Chelsea has set high target for this team that they want Chelsea to compete for Champion league zone and as long as they can able to managed their consistency i think Chelsea will finish at top 4
