With the injury record Jonny Evans, Phil Jones and Chris Smalling have, asking them to fill the void left by the departures of Nemanja Vidic and Rio Ferdinand this summer was probably not clever from the club.
They signed Marcos Rojo while Tyler Blackett has had to be used on numerous occasions. Previously unknown Ulsterman Paddy McNair has even been thrown into action.
Yet they had opportunities to buy quality centre backs. Nicolas Otamendi, Eliaquim Mangala and of course Ezequiel Garay.
The Argentine was a long-term target for United and when he inevitably left Benfica many always assumed it would be to join the Red Devils.
That did not turn out to be the case. Zenit St Petersburg got the leap on their competitors by snapping him up first, paying €15 million for his services.
Now it is clear to see what they are missing out on as Garay continues to out in excellent performance after excellent performance for the Russian side.
But this week rumours of a renewed interest are doing the rounds.
It is being reported that Manchester United have sent scouts to see him in action recently, so a bid is noe being lined up.
Which of course seems dubious.
Zenit are not a team struggling for cash. They will not be asking for anything near the pitiful amount United would have had to pay this summer gone. They are more likely to be asking for at least double that considering his long-term future is penned to the club and he only arrived a couple of months ago.
Even if Zenit were prepared to sell, which they won't until the price reaches silly money - it would simply be bad business from United were they to sign him now, just months after they could have got him for around £12 million..
They won't pay it, Zenit won't sell and Garay is not going anywhere.
