Manchester United defender Lisandro Martinez has launched a rare public criticism of the club's senior management following a disappointing 2-0 defeat to Atletico Madrid in the UEFA Champions League, questioning whether the leadership has done enough to strengthen the squad and support manager Michael Carrick.
The Argentina international expressed his frustration after Tuesday night's encounter at the Metropolitano Stadium, where United suffered another setback in what has become a difficult start to the 2026/27 season. Martinez suggested that the club's struggles reflected deeper institutional problems, insisting that responsibility for poor performances should not rest solely with the coaching staff and players.
Atletico Madrid took control of the encounter almost immediately when Pablo Barrios opened the scoring inside the first minute, leaving the visitors chasing the game from the outset. United attempted to recover but faced an increasingly difficult challenge after defender Leny Yoro received a red card in the second half. Ademola Lookman subsequently added a second goal to secure victory for the Spanish side and deepen United's troubles.
Speaking after the match, Martinez described the performance as unacceptable and questioned the direction in which the club was heading. The 28-year-old defender acknowledged that players needed to improve their performances but argued that the leadership also had a responsibility to ensure the squad possessed sufficient quality and depth to compete against Europe's strongest teams.
Martinez specifically questioned the work of Manchester United's director of football, Jason Wilcox, expressing disappointment with the club's transfer activity during the summer window. He argued that the progress achieved during the previous campaign should have provided a foundation for further improvements rather than leaving the team vulnerable to stronger opponents.
The criticism comes despite United spending approximately £155 million during the summer transfer window, bringing in Carlos Baleba, Andrey Santos and Youri Tielemans. Goalkeeper Karl Darlow also joined on a free transfer from Leeds United. However, Martinez's comments suggest concerns remain over whether those additions adequately addressed weaknesses across the squad.
Manchester United had entered the new campaign with renewed expectations after an encouraging finish to the previous season under Carrick. The former United midfielder guided the team to 12 victories in 17 matches, helping secure a third-place Premier League finish and qualification for the Champions League after a three-year absence from the competition.
However, that optimism has quickly faded following a series of disappointing results. United have managed just two victories across all competitions this season, while their domestic performances have produced the club's poorest start to a league campaign in four decades. The defeat in Madrid extended their winless run to five consecutive matches, increasing scrutiny of Carrick's leadership and the club's long-term sporting strategy.
Martinez defended Carrick against suggestions that another managerial change could solve the team's problems. He argued that United needed to examine decisions made beyond the technical bench, particularly in recruitment and squad development, rather than repeatedly replacing managers whenever performances deteriorated.
The defender also warned that successful teams must continually evolve because opponents become increasingly familiar with their playing systems. According to Martinez, United had failed to build sufficiently on the progress made last season, leaving the squad struggling to maintain the standards required at the highest level.
His remarks represent an unusually direct challenge to the club's leadership from a senior first-team player. While footballers frequently acknowledge disappointing results and accept responsibility for individual performances, public criticism of recruitment decisions and senior executives is less common, particularly during a period of mounting pressure on the manager.
Carrick, responding to the comments during his post-match media duties, suggested that Martinez's frustration might have been influenced by the disappointment of the defeat. The United manager explained that he had not watched the complete interview and would need to understand the defender's remarks before deciding whether further discussions or action were necessary.
Despite the result, Carrick maintained that his players had demonstrated commitment and created opportunities that could have changed the outcome. He pointed to several promising attacking situations and questioned the decision to dismiss Yoro, arguing that the match might have unfolded differently had United converted their chances.
The controversy has also attracted criticism from former Manchester United striker Wayne Rooney, who questioned whether Martinez should have expressed his concerns publicly. Rooney acknowledged the importance of strengthening the squad but argued that disagreements involving club management should generally be addressed internally rather than through post-match interviews.
Former Liverpool defender Jamie Carragher also criticised the timing of Martinez's remarks, warning that the comments could intensify uncertainty surrounding the club. Their reactions highlight the delicate balance between players expressing genuine concerns about institutional leadership and maintaining unity during periods of poor performance.
The dispute comes at a particularly sensitive moment for United, whose return to Champions League football was expected to signal a period of renewed competitiveness. Instead, the club finds itself confronting questions about recruitment priorities, squad depth, tactical development and the effectiveness of its sporting leadership.
Further reporting on Wednesday indicated that Martinez's concerns about recruitment and squad depth were shared by other members of the dressing room. However, his public intervention has also raised questions about his own future, with the defender approaching the final year of his contract and reportedly considering a move away from Old Trafford.
For Manchester United, the immediate priority will be reversing their poor results while preventing tensions between players and management from becoming another distraction. Carrick faces the challenge of restoring confidence within the squad, while senior officials must contend with growing questions about whether their recruitment decisions have provided the resources necessary for sustained success.
Martinez's criticism has added another dimension to the debate surrounding United's difficulties, shifting attention from performances on the pitch to decisions made behind the scenes. Whether the club responds through internal discussions, changes to its recruitment strategy or renewed backing for Carrick could prove significant as United attempt to rescue their season.
