That is the thing we disagree about. The progress being made is only if we consider a specific part of the season. We had them under every manager (except probably Moyes, but even with him we had 0-5 away victories in UCL). We won 6 matches in a row with LVG in the same season we destroyed Spurs, Liverpool and City within 2 weeks.
If we consider the season, I fail to see the progress. On par to have our joined worst number of points in the history of EPL. If we somehow win all the remaining matches, great we reach UCL. With that number of points we would have reached UCL in 2 out of the last 10 seasons (and once because of GD). From 4 signings, we have 1/4 hit, 2/4 decent but vastly overpriced signings, and one that looks like a Championship player. Decent, but hardly great (we had decent but hardly great signings under every manager). He put Greenwood and Williams on the team, the first one is actually great, the second one is decent. Again, pretty much every manager did so. Mourinho put McTominay, Van Gaal put Rashford and a dozen others, Moyes put Januzaj. Yes, Greenwood is better (though Rashford is still ahead of him), but that is simply cause he is better.
Looking at the entire season, we have had the mediocre average season we are used to getting for the last decade, and we are likely gonna be in the European minion league again. Yet people claim that we're third-best team in the league (and comfortably so) and are gonna challenge for the title next season, when we are closer to getting relegated than winning the title (check the table if you don't believe me).
