16/17 had some nice moments, mostly the zlatan-pogba connection, but that didn't last long. and most of the cup games were dull/lucky, and except city, all against average teams. Apart from the trophies, definitely should be nowhere near these lists.
This one (Barca over 2 legs, that Liverpool win after starting 0-0-2, Arsenal and City at home, strong runs in all the cups, Martinez, Casemiro) is the clear favourite. Shocking away record, especially against the big teams - maybe the season with the biggest difference between good and bad form?
Fun football for parts of 14/15, 17/18, 19/20. Some good games including against big teams in them. 14/15 had the liverpool double including juanfield, 3-0 spurs, 4-0 qpr, 4-2 city. 17/18 had a few 4-0s to start the season, the ridiculous title-denying 2-3 vs City's best team ever, and Herrera's hatchet job on Hazard. 19/20 had the double over city, 4-0 Chelsea, and that smooth lockdown football.
Even small bits of 18/19 (Ole's 3 months) and 20/21 (Spurs, Milan, Roma) were good. And liked watching Martial and Rashford emerge in 15/16. Smalling and Blind, world-class CB pairing
Moyes and last season had zero redeeming features.
