It's so easy to forget just how toxic those last few months were.
Under Roberto, we took the classic one step forward and two steps back. He kept making the same mistakes week in week out, but everything was phenomenal according to him. His press conferences became more and more bizarre.
The team lost discipline and was largely unfit because of him. His backroom staff was also uninspired.
He had a good first season bounce, helped by the stability left by Moyes, but the negatives just wracked up thereafter. He simply had to go.
