Back in the Autumn, David Moyes revealed why he chose not to pursue a deal for Mesut Ozil when he was reportedly offered to United back in August.
ESPN reported: "We didn't need that position at the time. I didn't even say it was an interest, it was put to us and it was just something at the time we didn't need.
"We had Shinji Kagawa and Wayne Rooney and people of a similar ilk so it wasn't quite what we required at that time. We were looking at different positions."
Months on and Manchester United are tracking a trequartista of their own, Chelsea's out of favour Juan Mata.
While United's official word is they have not made a bid, a £37 million offer is mooted, with Chelsea claimed to be willing to deal at £42 million, report The Independent.
Mata's suggested arrival has already been questioned by ex-Red Gary Neville, who described Mata as being a ill-fitted in terms of United's playing style.
With Mata's ideal position in a central role behind the striker, the same favoured by Shinji Kagawa and Wayne Rooney, the same questions which caused David Moyes to walk away from the chance to sign Ozil, exist with regard to the Chelsea man.
It is not a stretch to suggest the interest in Mata is an admission from David Moyes he was wrong to turn down the chance to sign Mesut Ozil in August.
Shinji Kagawa has been a disappointment all season long, while Wayne Rooney has also had his own injury issues.
Yet the impact and feel-good factor of Ozil's arrival at Arsenal, and the benefit it has had on the whole squad is one United sorely missed in the summer, and may be hoping the acquisition of Mata will bring now.
It could be too little too late with regard to this season, but David Moyes may well wonder what would have become of both United's and Arsenal's seasons had the German international headed to Old Trafford rather than the Emirates.
