It is actually kind of sad to see Postecoglou’s Man fighting with Aston Villa to stay in the fourth position when they were showing good signs at the start of the season and almost looked like they were going to give good competition for the English Premier League title. From mid February they are trying to occupy this position, now I think they are going to finish in the fourth position. Because they have a good advantage over Aston Villa as they have played one match less compared to them.
Aston Villa have a long amazing adventure this season but in quality, they are worse than Tottenham Hotspur and in depth of player resources between two clubs, Tottenham Hotspur are better too.
Aston Villa still don't lose all chance to get a fourth position and there are some matches and opportunities for them to reclaim it from Tottenham Hotspur. Aston Villa have a big disadvantage as they already played one match more than Tottenham Hotspur while two clubs have same total points.
Also, Aston Villa is not in good form right now because they have only one win in the last five matches. But I think they will be able to improve because right now they do not have any pressure from the teams that are below them. The team wages right below them is Manchester United and there is a difference of 11 points between them. By the way, Manchester United is also not in good form at all.
Aston Villa will have to pay attention on their dual race with Tottenham Hotspur and they don't have to care too much about Manchester United. Risk to lose the fifth position to Manchester United is very small and I believe Aston Villa will be able to defend it successfully.
