A couple of things that have bugged me tonight, other than the obvious ie subs, lack of clear gameplay to break them down etc.
Not playing Fred, who has been one of our better players this season. Has only started 2 of our last 6 games. Why does he need so much rest? Apart from beating Liverpool, we've been very laboured in general over the last few weeks.
Another strange decision was moving Rashford around so much when in good form, and he's been gradually getting worse. We finally put him back into his regular position tonight and, lo and behold, he's crap. Played him into bad form. He's needlessly messed about with things like that and now we're suffering.
