Lisandro Martínez apologized to Manchester United's leadership and manager Michael Carrick after criticizing the club's summer transfer window strategy. His initial outburst followed a 2-0 Champions League loss to Atlético Madrid, where he publicly blamed director of football Jason Wilcox for insufficient squad strengthening. Martínez expressed frustration over the lack of investment, particularly in areas beyond midfield, despite the club spending £155m on Andrey Santos, Youri Tielemans, and Carlos Baleba. The defender's apology, issued on Instagram after a meeting, acknowledged his passion and that his comments were made at an inappropriate time. Manchester United is expected to fine Martínez, though disciplinary actions remain private. The wider squad reportedly shares Martínez's concerns, contributing to a poor start to the season, with Carrick facing significant pressure after the club's worst league start since 1986 and an early Carabao Cup exit to Brighton.
