Just how crucial could that comeback win over Roma in the Champions League be for Manchester United and for Michael Carrick's job?

If United rediscover the level they managed to find against the Serie A side in the second half earlier this week and get a win this afternoon...It could prove to be a massive turning point.

Matheus Cunha scored two goals and was massively fired up, so much so that he was sent off for a second yellow card for excessive celebration.

If United can find some of that intensity and desire, will things improve?
