David Moyes got to where he is by being ruthless.
It has been 26 years since United last needed to find a new manager, and the fact that a legend like Sir Alex Ferguson has entrusted the former Everton supremo with absolute power means that Moyes most definitely has the potential to thrive at United.
That said, one has to question some of the decisions he has already made, just three weeks into his tenure.
While most people were absorbed with the whole Wayne Rooney scandal, Moyes somewhat slyly announced his intention to keep the erratic Nani at the club by handing him a new lucrative contract.
One has to wonder, did Moyes even watch Nani play last season?
In no uncertain terms, last year, Nani was abysmal. Between getting injured every few weeks and getting sent off against Real Madrid, Nani doesn't seem to be ingratiating himself to the United faithful.
While much has been said and still can be said about his undeniable potential, we have to wonder: is it even worth it any more?
True he can put in a spectacular performance worthy of any Champions League final every once in a while, but is that enough?
The undeniable conclusion is that he isn't worth the time. Six years ago, when he was a precocious 20-year-old talent, fans could tolerate this vicious cycle of periodic overachievement supplemented with sprees of rabid underachievement.
When he was 20, a stunner in Middlesborough could negate a series of five games in which he failed to complete the most basic dribbles.
Even when he was 22, we could still tolerate stinkers against Chelsea and Tottenham if he skinned Arsenal alive.
Well he's almost 27 now. He hasn't turned out to be the spectacular player that his compatriot at Real Madrid became.
Quite simply, he isn't worth the trouble anymore. When he was young, management could blame his immaturity for his lack of consistent form.
There was even a period a couple of year ago when it seemed like Nani might finally become the player that United so desperately hoped he would become.
This too, however, passed and the erratic, sputtering Nani returned.
Surely a £100,000 a week can be better spent on youth or investment into a better alternative.
Nani has proved time and time again that he just isn't worth the time, effort, and money put into him.
It's time for a change at United and getting rid of Nani should be the catalyst to this.
Moyes has - for some reason - put his faith in Nani even after his dismal track record.
So I will issue this challenge: Prove me wrong Moyes. Show me that you aren't wasting money on Nani's wages.
