The Barcelona 4-0
Season 19/20, early season we somehow kept grinding out wins from everywhere [mentality monsters], the Villa 2-1 was the most notable, then battered Leicester 4-0 on Boxing Day [could have been 8 or that night], & we had a massive lead [around a 20 point lead] at the top of the table by the end of January, then covid hit, & the league didn't restart until the end of June, & finally ended up winning the title after 30 years.
