Man, its good to finally be able to post on this site instead of just lurking and all.
Anyway, I looked up Wesley's expected goals stats for the past 3 games, and he's actually number 7 in the list of Villa players. Grealish, Mcginn, El Ghazi, Trezeguet, Hourihane and even Davis have a higher expected goals talley in the past 3 games than our current top man. Davis has somehow accrued a higher expected goals talley in a total of 30 minutes of time in the last 3 games than Wesley has had in 241 minutes of the last 3 games. Now, that's not to say Davis would actually meet that expected goal talley since his finishing is crap but its still pretty interesting how low it has been and highlights how unlikely Wes was to score in those 3 games even compared to other Villa players.
If you include the last 5 games, which includes the famous Norwich game, then his stats jump up considerably, so much so that Wesley is number 1 in terms of expected goals which really highlights how much that Norwich game did to improve his stats in general. If you increase the scope to include the last 10 games and all games in the PL so far, Wesley is shown to still be comfortably number 1 in terms of expected goals too. I checked his expected goal talley in that individual Norwich match, he was expected to have 2.62 goals in that one match, which makes sense when you consider how many goals he actually got and the missed penalty. But his actual expected goals talley throughout the whole season aside from this match has actually been at around 2.4. In short, Wesley's expected goal talley in the last 10 games if you discount the Norwich(but including the Everton match where he also performed admirably) is less than the expected goals he accrued in that one singular game, giving him a goals per game talley of less than 1 out of 4 without the Norwich match and 1 out of 2 with the Norwich match.
What I'm trying to essentially say is that whilst Wesley can be amazing for one game, he tends to have many poor games in between. I do think he is very wildly inconsistent in terms of how good he can be in a game but he is far more likely to be poor in a game than to be great in one. Now I know this is generally the consensus of him anyway, but I just wanted to analyze this from mostly a stats perspective. Are we really in a position where we can afford to place a striker who is going to score loads of goals in 1 every 5 matches(this is already a pretty generous ratio in my book considering he probably isn't going to be up against a backline as poor as Norwich's every 5 games) but be largely crap in those other 4 matches? And this is mostly from a goal scoring perspective as well, which is the main argument for Wesley, I too agree with the notion that he generally doesn't seem to do the other parts of the game all that well either.
