For me this is one of the improvements for Chelsea even though the opponent they face is only a team from the bottom of the standings. But believe me Wolves is a team that always knows Chelsea's weaknesses and can make it difficult for Chelsea to win. So in this match Chelsea can get 3 points, meaning Chelsea has tried to improve its performance to continue its stable consistency as before.
After some disappointed matches, this win can help Chelsea returning to its right track, for competing top four of Premier League with some other clubs. With same 22 played matches, the competition for top four includes many clubs from Arsenal, Nottingham Forest, Chelsea, Manchester City, Newcastle United, Bournemouth and Aston Villa.
We can see from Aston Villa at 8th position, it's only 4 points less than Chelsea at the fourth position, and 8 points less than Arsenal and Nottingham Forest at second and third positions. Many changes will happen with these clubs from second to eight positions in next weeks.
Yea many changes can take place between the top eight teams to the second position because no team is guaranteed a place in the top four as of today and with the way Manchester city is recovering back to the Manchester city we all know, let's not be surprised if they pull something extraordinary and win all their remaining fixtures, and if they can do that, they might even finish in the second position if care is not taken, though it can be difficult, but it's not impossible.
Then as for Chelsea getting back on track? It has been long overdue, they really need the winning to bust their confidence level and the reliance on Nicolas Jackson for goals is actually costing then because Nicolas Jackson is not that striker that is going to fire them to the title, before he scores a goal, he might has missed a whole lot of opportunities that may have comes begging, so it's very important that Chelsea address that position by signing an attacker this January if it's possible, because I don't even think that if things are being left with Nicolas Jackson he can fire the team to the UEFA champions league, but nevertheless that's one major area of the pitch Chelsea really needs to improve in the transfer market if they really want to compete against the other top teams.
