It's very unfortunate that what happened to Aston Villa this week, they could have maximized a bigger opportunity to become leaders of the standings, but unfortunately they failed to win the match against the bottom team. I think the Aston Villa team was very confident and underestimated their opponents so they didn't get maximum results.
The draw result in the Liverpool and Arsenal match was very fair, both teams have shown their best performance and indeed these two teams have almost the same strength so sharing the points this week is very fair.
Since looking at this week's match schedule, I have been optimistic to see that Aston Villa has an opponent that Unay Emery troops can handle easily rather than the big Liverpool vs Arsenal match which is sure to be tough. Instead of taking advantage of this situation Aston Villa actually underestimated Sheffield United defense and had to share the points, even though they were lucky to have a chance in the final minutes. In my opinion Aston Villa finds it easy to face Sheffield United at home where Aston Villa home record always ends with extraordinary results. However the result was surprising because the first half was not used to score a goal this is what Unay didn't realize was wasted time. After Cameron Archer opening goal in the 87th minute, Aston Villa started to play aggressively.
