The change that occurred at Aston Villa is of course Unai Emery expertise in managing his players to perform better in every match they play. Their progress has been unstoppable so far because they were able to beat two big teams, namely Manchester city and Arsenal. They managed two difficult matches well by achieving a victory that allowed them to compete at the top of the standings. We see their game getting better in every match because they are increasingly confident to get up and do their best with their targets this season.
I think their big target is to lead the standings this season because Aston villa are slowly being able to overtake the teams above them. The next two matches will be easy for them if compared to the previous matches. But I hope they don't get complacent too early because this season still has a long way to go and many surprises could happen in the coming week.
Unai Emery's good managerial skills and effort in taking Aston Villa to the top 4 in the EPL standings has shown that the Aston Villa board made the right choice of replacing him with Steven Gerrard, infact he's a very big upgrade to Gerrard and has really tried his best to get the best of his players that's why they're performing pretty good on the pitch and even above Manchester City in the standings currently.
Aston villa has made the villa Park a fortress this season, they're in a very good form at home and are yet to concede defeat even against the very big teams of the league, about yesterday they defeat Arsenal to add to their home winning streaks and if they continue this good form both home and away there's a possibility of them getting to the top of the league, because they're currently in 3rd position with about 35points just 2 points behind the current league leaders Liverpool.
