Man Utd player Alexis Sanchez has played all six games on the left but a move to the right could yet get more out of his team-mates.
On paper, it has been a fairly encouraging start for Alexis Sanchez: two man of the match displays, two assists and a goal in his first six games. Not bad for a free transfer
Sanchez has quickly established himself as a fans' favourite - one of the few players who regularly gets supporters at Old Trafford off the edge of their seats - and always looks to make something positive happen. That is partly why he loses the ball so much.
But United's new-look attack, which enjoyed such a slick start to 2018, has not really clicked yet and lacks a little bit of balance with Juan Mata, Jesse Lingard and Anthony Martial fighting it out for two positions.
There have been glimpses - Sanchez and Romelu Lukaku linked up brilliantly for United's second goal against Huddersfield while there have been some neat triangles involving Mata and Lingard - but it is going to take time.
Tellingly, before half-time at the John Smith's Stadium on Saturday, Lukaku and Sanchez had a constructive exchange during a break in play, with lots of gesticulating, as they attempted to get on the same wavelength.
That eventually happened when Sanchez's sumptuous dink set Lukaku free to book United's place in the quarter-finals of the FA Cup. Lukaku immediately thrust a grateful finger in the Chilean's direction as he jogged over from the halfway line to celebrate with his team-mates.
That was pure instinct from Sanchez - knowing Lukaku would make that run - and, contrary to popular belief, Mourinho likes to see that natural intelligence from his forwards.
Mourinho sets out to trust his forwards' instincts, that ability to pull a rabbit out of the hat, and that is partly why he values Juan Mata, and his football brain, so much.
That is also why Mata has been given licence to roam and drift inside rather than hugging the touchline like a traditional right winger.
Mata endured a frustrating night when United relied on the counter vs Sevilla
It is a policy Mourinho's mentor, Sir Bobby Robson, also adopted although the former Barcelona manager took it to remarkable extremes, even trusting his players to decide who to pick up at set-pieces.
That would never happen under Mourinho and while he is happy to trust his forwards' intuition, a winger can't succeed under him unless they track back and help out their team-mates without the ball, too.
That is something Sanchez tries to do - you can hardly fault his work rate and he was one of the few to shine in that dismal defeat to Spurs last month - but his forward runs constantly left Luke Shaw exposed at Huddersfield.
The Terriers got so much joy down United's left-hand side as a result, particularly in the first-half, and at one point Mourinho even took to pointing his new signing to the run of winger Collin Quaner to help him out.
So how can Mourinho shake his attack into life ahead of a run of season-defining fixtures against Chelsea, Crystal Palace, Liverpool, Sevilla and Brighton?
Manchester United found their perfect right winger
The obvious answer would be to switch Sanchez to the right, his natural side and where most United fans expected him to play before he joined the club, and move Anthony Martial back into his favoured left-sided role.
Whatever about Paul Pogba's nose being knocked out of joint since Sanchez's arrival, Martial has struggled in the Chilean's shadow. After a brilliant start to 2018, when he was directly involved in five goals in the first four games of the year, the 22-year-old has failed to impress ever since.
Shifting Sanchez to the right would also allow Mata to move inside to his favoured No.10 role; the Spaniard has performed admirably on the right, but he does not offer that lightning pace on the counter that could rip teams apart.
Mourinho will have spoken to Sanchez about where he will play in his side and he will have surely promised him he would get the opportunity to play in his favoured role on the left, where he loves to cut inside onto his right foot.
But the overall chemistry of United's attack has suffered as a result and those issues on the right, where they lack a natural presence on the counter, will not go away.
