Chelsea and Aston Villa has similar points on the table and I can't even differentiate their performance but I think Aston Villa are sneaky team that make way even when things are difficult for them. They just humiliated Bayern Munich in the Champions League and draw almighty Manchester United in their last game and as for Chelsea, they are busy making more goals than what they have concede, only their next matches is going to determine who is going to last at the top.
This season Chelsea performance has be become great a performed compared to the last season how they was so performing very poorly, this season chelsea area able to conceded a lot of goals after wining several matches they’ve played; as it now Chelsea is maintaining the 4th position in the table, and now that Aston Villa is behind of Chelsea with the same points they need to maintain their consistency against their match, because that’s the main problem that there was facing in previous seasons.
By features arrangements, Aston Villa might have a way to stay above Chelsea because I'm not sure how Chelsea are going to win Liverpool that is fighting to stay ontop of the table, any small mistake from this play will not only drag them from there, they have to come down to stay with Aston Villa hopefully Villa don't win their next matches again but sometimes, things don't go as expected, minor teams don't finish from surprises.
Since Chelsea are able to make some improvements this season they might not find the match so difficult, even thought the Liverpool is going to win them they can also try their possible to reduce some pressure for the Liverpool; because for now Liverpool have dominated the La Liga by claiming the top of standing.
