If Manchester United are to continue their current revival and really sustain a lengthy title challenge, one gets the feeling that they are going to need to bring in players who aren't just skilled with the ball at their feet, but also have the head to be able to cope with the pressure upon arrival.
That instantly cuts the list of potential targets for the January transfer window more than in half, as there really aren't that many players who will be affordable, whilst also assuring instant quality and the promise of success.
Alternatively though, the biggest mistake they could make would be to shell out a large amount of money on someone who could just as easily fail to make the grade as turn the tide of form in their favour.
It's this prevalent point that leads me onto the rumours lie at the heart of this particular argument.
It makes sense for David Moyes to be following certain established stars, who have excelled in their respective leagues and can be depended upon to slot into whatever role they need to and immediately begin to show results. That's why it's all the more surprising to hear that they're hot on the tails on former Chelsea ace Nemanja Matic.
The 25-year-old has rebuilt his career at Benfica, and is one of the best playmakers in the Portuguese league. However this shouldn't constitute a chase from the powers that be at Old Trafford, and it most certainly doesn't warrant them paying anywhere close to his £42million valuation.
True, he is the sort of advanced playmaker who Moyes will be looking to slot in alongside the likes of Michael Carrick and Marouane Fellaini, but he is not experienced enough to go from playing in the Portuguese Liga to competing under the strenuous pressure at the Premier League summit, and be expected to efficiently thrive.
Reports are suggesting that the Serbian's price-tag could be realistically bargained down until it stands at nearer £18million, but in my mind that's a better part of £20million that Moyes could most definitely put to better use.
What United need right now is the brand of player synonymous with the likes of Ilkay Gundogan and Paul Pogba. They need a player who is capable of slotting in the hole between the midfield and attack and link the two seamlessly.
Though Matic may be capable of fulfilling the role with Benfica, the standard between the two respective leagues in Portugal and England is sufficiently different to be able to determine that he may struggle with doing the same if a move were to come to fruition.
If he were to transfer somewhere such as Chelsea or Manchester City, ironically the mass competition for places might benefit him in the long-run, due to the fact that he would be afforded more time to settle before he was expected to perform, to a certain degree at least.
In stark contrast, anyone who arrives at the Premier League champions in January will have to be prepared to be thrown head-first into the deep-end, and subsequently run the risk of following Fellaini into the realms of the unsuited and ill-prepared.
In short it's obvious that United need to spend the money that their manager has been gifted for the winter transfer window. However in my mind it's more a case of who they buy rather than how much they spend that will have true leverage on the success or failure they experience in the months following.
