You cherry picked all the terrible moments, good for you. However every team that didn’t win the title has a lot of similar moments, if you want to be negative you can.
On the positive side we smashed Chelsea, beat united and Mourinho, knocked both City and Chelsea out of the FA cup in consecutive rounds on our way to winning the whole thing. We scored a shit load of goals a lot more than in previous seasons, Holding developed into a great looking player, Iwobi as well.
Combine my positives and your negatives and we have a pretty decent season. The scum won a lot of matches and still have absolutely nothing to add to their barren trophy cabinet. We supposedly had a worse year but won something regardless.
