Bruno Fernandes has transformed Manchester United over the 12 months.
There's good reason to think that Ole Gunnar Solskjaer wouldn't be in the technical area at Old Trafford right now if it wasn't for the midfielder's arrival from Sporting Lisbon in January 2020.
Besides, only Liverpool's Mohamed Salah managed to score more goals than Fernandes in the Premier League in 2020, which is nothing short of astonishing given the Portuguese's position.
January signings
And it's certainly no coincidence that United have only actually lost three times in the Premier League since his arrival, sparking claims of a potential title challenge in 2020/21.
As a result, Fernandes is rightfully being considered as one of the greatest January signings in the history of England's top-flight with the window having been inaugurated in 2003.
And while we all have our own opinions on who the finest purchase really is - lest we forget that the likes of Nemanja Vidic and Patrice Evra were winter buys - stats have now settled the debate.
Most impactful mid-season buys
Well, at least they have in one respect with a study from BettingOdds.com assessing who the most impactful mid-season signings of the last 20 years of Premier League football have really been.
Their first half-season and its impact on the team is how the players are being judged, so don't panic about the absence of Virgil van Dijk and Luis Suarez who came into their own a little later.
But without further ado, you can check out the most impactful January signings in Premier League history down below, which we suspect will go down pretty well with the Old Trafford faithful.

Fernandes takes top spot
So, there you have it, any doubt surrounding Fernandes' impact at United can be dispelled by the simple fact he changed the Red Devils more than any other mid-season purchase before him.
It's also interesting to see the amount of signings from the early 2010s that make a cameo with Cisse, Sturridge, Bent and Jelavic reminding us of a very nostalgic Premier League era.
And while, yes, attacking and midfield players certainly seem to have an advantage in the study, fair play to Monreal and Skrtel for breaking the mould with their impacts at Arsenal and Liverpool.
But in the iconic words of Nigel Pearson, you're an ostrich if you don't think Fernandes has changed the game at United, regardless of how much penalties are to thank for it.
