It is a question as old as time itself: how do Manchester United get the best out of Paul Pogba?
The Reds beat competition from Europe's biggest and most affluent clubs when they re-signed the Frenchman in an £89m deal back in 2016 and, contrary to what some believe, he has been a good signing for the club.
In terms of natural talent and ability, Pogba is United's best player and a major factor behind his struggles to find consistency in his performances is that United's managers have been unable to create an effective framework from which he can thrive to his maximum capacity.
That Pogba has excelled previously in a Juventus side which dominated Serie A and a France team that were crowned world champions in 2018 shows that he can be a huge asset if used in the right way and surrounded by players of similar or equal ability.
United certainly are not at the level that Pogba would have expected them to be when he agreed to return to the club but the signing of Bruno Fernandes is a hugely positive step in the right direction. Once Pogba has returned to full fitness, his relationship with Fernandes will be key to the team's chances of success under Ole Gunnar Solskjaer.
There has been a long-held belief that Pogba's best position is as a left-sided central midfielder in a 4-3-3 system, but that is not strictly true: he has performed capably in a variety of roles and different systems in the past, such as in a 3-5-2 or 4-3-1-2 at Juventus or in a double pivot with N'Golo Kante in a 4-2-3-1 for France.
It was at Juventus, though, that Pogba announced himself as a top-class talent. Barring injuries, Juventus predominantly played a 3-5-2 system throughout Pogba's four-year spell in Turin, largely because of the unyielding strength of their defensive four comprised of Gianluigi Buffon; Andrea Barzagli, Leonardo Bonucci and Giorgio Chiellini.
In that system, Pogba's main role was to help Juventus in transition phases by using his energy and dribbling ability to drive the team forwards, rather than act as the team's chief playmaker as has been expected of him at United. In each of his four seasons at Juve, Pogba ranked in the top three players at the club for dribbles attempted, while his highest rank for chances created was sixth in 2015-16.
Andrea Pirlo was Juventus' deep-lying playmaker but there was also a big creative onus on one of the two forward players to fashion chances, initially Carlos Tevez and then in Pogba's final season, Paulo Dybala. Tevez was in the top three for chances created in Juventus' squad in his two seasons, while Dybala was their second-most creative player in 2015-16.
During Pogba's time on the sidelines, United have, for the first time since he's been at the club, experimented with a back five with wing-backs and to good effect too. And with Fernandes making an immediate impact as United's main creator - he has created 11 chances in the Premier League, more than any other United player - Pogba can reprise his Juventus role with Fernandes playing as a second forward, similar to Tevez and Dybala.
Fernandes' signing has been a game-changer for United, but it could also have a seismic impact on Pogba's form too. With the Portuguese playmaker assuming creative duties, Pogba can strip back his game for the good of himself and the team.
It is a combination that has the potential to work wonders for Solskjaer's side.
