It was actually two years.
In 20/21 his performance levels dropped through the floor and he was also being very lazy, but he still managed to score and assist quite a lot to somewhat hide that. It's why a lot of people were already worried about him after that season. It's a good attribute to be able to get goals/assists while playing badly, but there's only so long that it can last. Either he would have to kick back into form or the goals would dry up.
Unfortunately it was the latter as we saw in 21/22. He continued being extremely lazy and playing like shit, and now there weren't any goals to hide that.
This season so far there's been a bit of both. Some games where he's actually played very well, some where he's been shit. It's an improvement over where he has been the last two years but I don't get people talking as if he's back to his best. Fingers crossed that he can get there but he's certainly not there yet.
That's just not true. He started 20/21 on fire and was very good both scoring and linking up play. There were genuine Ronaldo/Mbappe comparisons brewing. Then he got his back injury and then he never really looked the same since until this season.
Also people are forgetting that he had basically not had any rest since the COVID break. He had no real chance to recover properly from his injuries.
He was great when football started post COVID, had barely any rest in summer because the next season started immediately. Was really good for the start of the 20/21 season... started picking up injuries around December and continued to play through them until he finally broke in January (at that time he was our best attacker and almost at a goal a game). He rushed back towards the end of the season but he just wasn't the same. Lost EL final in a penalty shootout.
After this season he seriously needed to rest and fully recover. But he went to the Euros, basically lost them for England with the missed penalty and was mentally shot.
I wouldn't blame him at this point to have a really bad next season. He'd basically been playing for over a year without any rest and was starting another one immediately while not fully recovered and mentally having lost 2 finals via penalties.
Lo and behold he's shit next year. Other things are going wrong too.. like Ronaldo messing with the team chemistry, Maguire losing all form and confidence, Ole's stubbornness in playing his favorites through injury, etc. The result being he looks the worst he's looked his entire career.
Finally has a full summer break after this season. His FIRST since the first covid lockdowns in early 2020. He finally recovers from his back injury (which are notoriously hard to recover from), while he started the season slow he starts looking like his old self, has some of the burst and confidence back and looks less depressed about football in general.
None of this is very hard to see. But his supposed fans just didn't want to. Because to them players are just robots. He's lazy and shit and needs to be sold. T rashford. And now that he's starting to come back into it they come here still justifying their fair-weather tantrums to continue to hold his worst against him and define him by his worst rather than his best (which has been quite a lot for his age)
