It was short-sightedness to say Lingard was better than Alli in the first place.
Alli had a relatively average season last year, but still managed 9 goals and 10 assists, if Lingard gets that in the league it would be his best career return. Lingard had the best in his career last season and only managed 8 goals and 5 assists, I think it was always pretty obvious who had more talent and who would forge a greater career. Alli had just come off the back of a season where he scored 18 (!) league goals at the age of 21 ffs. Even when comparing a poor season for Alli and Lingard's career best, the difference really wasn't that stark.
Lingard was better in the World Cup, but it's not like he was that special .. scored 1 goal (same as Alli) vs Panama, worked hard and was good off the ball. Given the choice, would anybody really take Lingard ahead of him? I honestly don't mind Jesse and think he's a very useful squad player for United, gives it his all and scores the odd important goal. Fact is though he's blatantly not on the same level potential wise as Alli, who has genuine top level quality in him.
