Sure, Pogba is young (19), talented and full of potential. And yes, Sir Alex Ferguson was hoping to retain him as a future fixture in the Red Devils midfield.
However, with United's recent acquisitions and their ever-present appeal to transfers, this won't be a devastating loss by any means.
Man U has already made a big splash in the transfer window, signing Japanese midfielder Shinji Kagawa two weeks ago. Like Pogba, Kagawa is young (23) and after agreeing to a four-year contract, he will be a mainstay in Ferguson's lineup for the better part of this decade.
Unlike Pogba, Kagawa also is ready to contribute immediately. Pogba spent most of his time on the pine last season, making just seven appearances for United. Meanwhile, Kagawa was busy leading Borussia Dortmund to their second consecutive Bundesliga title.
The lightning-quick Kagawa was an offensive force last season, scoring 17 goals and giving away 13 helpers in Dortmund's title defense. He scored in nearly every way imaginable, using his quick feet, creativity and high football IQ to torch opposing defenses.
Kagawa isn't the only promising addition Man U made, either.
They also brought in Nick Powell, the England Under-18 international who scored 16 goals for Crewe Alexandra last season. Powell is an electrifying talent, and although he will need some time to adjust to the higher level of competition, he could be a major asset for United in the future.
Neither Powell nor Kagawa has the defensive presence of Pogba, but with their strong, current roster and ability to bring in world-class transfers, this won't be a big issue for United.
Obviously, Ferguson and company would have liked to retain the highly talented Frenchman. With their ability to reload, however, he was certainly expendable.
