As a lot of us have said in this thread this season, it sounds like it's just been one thing after another for Jack over the last few months and, because he's quite a sensitive lad, it's all probably hit him harder than it would most players. Started the season injured on and off but got a bit of form together just before Christmas with those three goals in three games (vs. Spurs, Luton and Palace).
But then there was the burglary and the injuries against Copenhagen and Luton, and before you know it we're in March and Pep is nailing down his best XI for the run-in and Jack's not involved. He looked particularly upset by the injury he picked up at Luton in the FA Cup because he knew it was approaching crunchtime and that he wasn't fit. He played well in the 4-2 win at Palace and was involved in all four goals but then he didn't start again for another two weeks.
At that point I imagine he's had a bit of a sulk -- when he was "unwell" before the Fulham game I did wonder whether there was something else going on behind the scenes. Sounds like him and Pep have had words this season -- nothing serious or fatal, but Pep clearly feels he's not applied himself as much as he should have this season. It sounds like Jack gets bored easily when he's not playing football and it's impacted him off the field this year.
Jack said himself after we won the league against West Ham that this has been the hardest time he's had at City, and his relatively muted behaviour at the parade -- compared to last year -- seems to back up that his mood is a bit low. Hope he can get back to his best next season because he really is vital to the best football this team plays. Winning four on the trot is unbelievable but you wonder if we'd have another trophy right now if Jack had stayed fit.
I do have hope for him next season because he'll have something to prove, and we saw what good that did him last season. I know he's not everyone's cup of tea in terms of what he brings to the team going forward, but his workrate and desire can't really be questioned when he's feeling good. Shame to not have seen the best of him again this season but you just have to hope a summer with England and coming back fresh will reinvigorate him.
