Forget the fact that there's been little midfield protection, the entire United back line need to take a good look in the mirror themselves before United start becoming a defensive laughing stock.
Nine goals shipped in six games is an embarrassing record, a far cry from Sir Alex teams of the past.
I realise I'm cheating here when four or five players constitute one pick, but it would be a struggle to name more than three Red Devils who don't need to improve (Alex Buttner, Paul Scholes, umm...the goalkeepers?).
It's just as much of a struggle to pick one out of Rafael (at least defensively), Rio Ferdinand, Jonny Evans and Patrice Evra as the villain at the back.
But this is Manchester United, write them off at your peril. They're in third place in the league, only four points behind an unconvincing Chelsea side—and that's having played football devoid of any inspiration. Imagine the possibilities if they play with just one more iota of passion.
Newcastle are next—hopefully last weekend's second-half fightback will galvanise the team into playing a decent 90 minutes worth of football.
If not, more difficult days lie ahead.
