According to a report by The Sun on Wednesday November 11, 2026, Mauricio Pochettino's potential appointment as Manchester United manager could have a significant impact on several players at Old Trafford, with some expected to benefit from his arrival while others could struggle to fit into his demanding style of football.

The former Tottenham Hotspur, Paris Saint-Germain and Chelsea manager has emerged as the leading candidate to replace Michael Carrick, whose position is reportedly under serious threat following Manchester United's disappointing start to the season.

Pochettino is known for his high-intensity football, aggressive pressing, quick transitions and willingness to give young players opportunities.

Those qualities could make him an attractive option for Manchester United as the club look to rebuild and return to competing for major honours.

However, his arrival could also create problems for some members of the current squad, particularly players who were recruited to suit Carrick's possession-based approach.

According to The Sun, several Manchester United players could experience contrasting fortunes if Pochettino takes charge at Old Trafford.

Among the potential winners is young winger Shea Lacey, who could finally receive more opportunities in the first team.

The 19-year-old has impressed in flashes this season, scoring against Brighton in the Carabao Cup and providing an assist in United's 3-2 Champions League victory over Roma.

Pochettino has developed a reputation for trusting young footballers, having previously worked with several talented youngsters during his managerial career.

Lacey's pace, confidence and attacking ability could appeal to the Argentine, who may see him as an exciting option on the wings.

Kobbie Mainoo is another player who could benefit from the managerial change.

The England international possesses the technical quality and ability to carry the ball through midfield that Pochettino generally values.

The former Tottenham manager has previously worked with energetic midfielders such as Moussa Dembele and Moises Caicedo, making Mainoo's qualities potentially useful in his system.

After returning to full fitness, Mainoo could become an important figure in the Manchester United midfield if Pochettino is appointed.

Lisandro Martinez could also receive a fresh opportunity under his fellow Argentine.

The defender's future at Old Trafford has attracted attention following his criticism of the club's transfer decisions and his recent red card against Chelsea.

However, his aggressive defending, ability to play out from the back and confidence in possession could make him an important part of Pochettino's defensive plans.

The Argentine manager has previously worked with technically gifted central defenders, including Toby Alderweireld and Jan Vertonghen at Tottenham.

Mason Mount is another potential winner, particularly because Pochettino was reportedly keen to keep him at Chelsea before Manchester United completed his £60 million transfer in 2023.

The former Chelsea manager viewed Mount as an ideal attacking midfielder for his high-pressing 4-2-3-1 formation.

His movement, work rate and ability to press opponents could make him valuable under Pochettino.

However, Mount must overcome his persistent injury problems if he wants to become a regular starter again.

On the other hand, Luke Shaw could find himself facing increased competition despite his previous relationship with Pochettino at Southampton.

The Argentine was reportedly a huge admirer of Shaw when the defender was coming through the ranks at St Mary's Stadium.

Patrick Dorgu could have an advantage in that position because of his energy, pace and ability to contribute both defensively and offensively.

Youri Tielemans and Andrey Santos are also among the players who could struggle if Pochettino replaces Carrick.

However, Pochettino generally prefers midfielders who can cover considerable distances, press aggressively, recover possession and carry the ball forward.

Tielemans and Santos could therefore face difficulties adapting to his preferred style, particularly if the manager decides to prioritise mobility and energy in the middle of the pitch.

Harry Maguire could also lose his place in the starting XI.

The England international has been a regular under Carrick, starting all ten Premier League matches this season.

However, Manchester United's defensive problems have continued, with the team conceding 19 goals.

Pochettino could consider giving younger defenders such as Ayden Heaven and Leny Yoro more opportunities, potentially alongside Martinez.

Maguire's lack of pace could also become a disadvantage if the new manager wants his defenders to operate with a higher defensive line.
