Didn't want to start a new thread just for some basic exploration and it was done to judge Mourinho's work so it's probably best here.
I was curious what the simple numbers looked like for the league performance shown within the 'big six' since Ferguson left the scene, to put in context the job Mourinho has - no matter what some of us may feel about his methods.
Three metrics are simply win%, win-draw% (unbeaten) and loss% in the league. Red is a step back from the previous season, green an improvement, amber is static. Added in the measures for this season so far as we draw towards the conclusion. Also included money spent (take that with a pinch of salt but I took it from the same sources for all teams) and trophies won since 2013.
I'll edit this later with more thought but generally, you can see the low level (even after his first season), Mourinho had to work with. Averaging only 19 wins a season (22 already this year) and 6 losses a season before this campaign. Although funny that Mourinho had the worst win% since Ferguson retired.
Also noticeable while we're the worst side in terms of average league performance, we're obviously not the only side struggling to maintain things from season to season if you look along the line. Also obvious what people mean by 'stability' with Wenger, given for four seasons straight they had the exact same % of losses in the league, simply swapping draws for wins (and vice-versa).
I think if we stay unbeaten and win at least 4 of our remaining games - that's 87% unbeaten and a 68% wins. Getting back up there with Ferguson's level before he departed.
