At the age of 20, Jadon Sancho is an elite player. He is in the world-class category, someone capable of scoring from anywhere, or picking out a teammate when seemingly nothing is on.
Last season, the Englishman scored 20 goals. He also created 20 assists in a breathtaking campaign where he set the Bundesliga alight.
It's hardly a surprise that a fee of over £100m to prise him away from Borussia Dortmund is being talked about.
There have been relentless reports touting him with a move to Manchester United and Old Trafford. It seems as though the wonderkid has been made Ed Woodward's number one priority this summer.
A move would be eye-catching and a statement of intent, especially for a club who have lost just once in their last 22 matches.
More is needed if the Red Devils are to return to their former glories, but landing someone of Sancho's quality would be a wonderful way to start.
Any side in world football would be lucky to possess someone with such quick feet and he'd surely be a success in the Premier League.
Of course, it was Man United's rivals that he left behind for German shores in 2017, but a return to the city that developed him so much as a footballer is beckoning.
Whether he walks through the door remains to be seen, but it's already thought that the winger would be happy with a switch. All that remains now, so it's claimed, is for a fee to be agreed.
Though, if Sancho does sign for Ole Gunnar Solskjaer's men, what would the consequences be for the rest of United's squad?
Here are three we've thought of...
Greenwood suffers
Another bright young talent, Mason Greenwood has arguably been the best up and coming player in the Premier League this season. He has burst onto the scene with devastating effect, racking up 17 goals in all competitions - ten of which came in the top-flight.
The youngster is a generational talent, the type of player who doesn't come out of your academy very often and after his breakthrough season, needs to build on the numbers he's produced and make sure it wasn't a one-season offing.
Though, if a player like Sancho arrives, it would surely be detrimental to Greenwood's development. Although he can play up front as well as on the flanks, United's frontline is pretty set with Anthony Martial and Marcus Rashford too.
If you're signing a player like Sancho, you're not going to leave him out. Thus, Greenwood could be the one to make way in the starting XI.
Martial becomes even better
The striker enjoyed his best season in English football to date this term, becoming one of Solskjaer's greatest success stories during his managerial stint at the club.
For a while, it looked like Martial would struggle to live up to the high expectations that were thrust upon him after moving from Monaco but he's now become a star for the Red Devils.
The Frenchman rattled the back of the net on 22 occasions this season and has clearly benefited from the creative talents of Bruno Fernandes. In 16 matches together, they've already combined five times for a goal.
Therefore, if you add someone just as creative in Sancho, Martial would surely get better. The Dortmund man has a remarkable record when it comes to creating opportunities, conjuring up 43 assists in 99 outings for Dortmund.
Martial should be licking his lips.
Wan-Bissaka can focus on defending
The full-back had a pretty solid debut campaign in Manchester but there is still a fair amount lacking from his attacking abilities.
His instincts are primarily to defend and he does so to excellent effect, performing 3.7 successful tackles per match. That being said, he manages just 0.4 accurate crosses a game, a number which clearly needs improving.
However, with Sancho in the side, a player who is as much focused on whipping balls into the box as he is with scoring himself, it could allow Wan Bissaka to sit back a little more, giving room for United's potential new signing to thrive.
The England international recorded 2.2 key passes a game in the Bundesliga this season - a mighty fine record and one that dictates he doesn't always need someone making the overlapping run - he is quite happy to carve out things for himself.
As can be seen from his heat maps (taken from SofaScore) in the last two seasons, he was charged with doing far more attacking after signing for United. The addition of Sancho, therefore, could push Wan-Bissaka into the more familiar role he played in at Palace.
For the time being, the positives of signing Sancho largely outweigh the negatives. Although Greenwood may suffer initially, it would be good news for Martial, Wan-Bisakka and the club's title chances.
