After enjoying a rapid rise over the course of this past year, Mason Greenwood finds himself in the England U21s squad for their games against Albania and the Netherlands. The Manchester United starlet was a part of the team that shocked PSG in the Champions League last season, and enjoyed a fine pre-season too, scoring against both Inter and Leeds.

In the limited game-time he has been offered by Ole Gunnar Solskjaer this season, the 18-year-old hasn't disappointed either, notching in full starts against FC Astana, Partizan Belgrade and Rochdale. Whilst he has impressed, one key concern surrounding the teenager is where his best position may lay. In his time with both the academy and the senior set-ups in the current campaign, Greenwood has played in four different positions: centre-forward, second striker, right-winger and right-midfield.

As per Transfermarkt, in his nine Premier League appearances, the United academy product has played as a right-winger on five occasions. This despite Solskjaer exclaiming that he is the most natural finisher the club has got on its books at the moment.

"Natural finisher? Well, they've (Anthony Martial and Marcus Rashford) still got a way to go, because Mason's more of a natural finisher than those two."

So when England U21s boss Aidy Boothroyd calls upon Greenwood over this international break, it will provide an intriguing insight to Solskjaer over where a fellow manager believes the prodigy can be best used. In the pressures of club games and needing to pick up wins at any cost, players' natural strengths may be sacrificed in order for the team's gain.

But in a far more relaxed environment, Boothroyd's use of Greenwood could open the United boss' eyes to where his best position may be in the future. The likes of Martial and Rashford have proven throughout their careers that they are more than capable of playing on the flanks (they have played on the left-wing 111 and 58 times respectively). That could allow the Red Devils' academy prospect the chance to stake his claim as an out-and-out number nine.

Whilst Solskjaer may cast a keen eye over Rashford's performances with England's senior set-up, he would do well to take notes from Boothroyd's handling of Greenwood over these next couple of U21 games.
