Man Utd's Martínez sorry for post-match outburst

Lisandro Martínez, Manchester United's 28-year-old Argentina defender, has issued a formal apology after publicly criticising the club's board, including director of football Jason Wilcox, following Tuesday's 2-0 defeat to Atlético Madrid. Martínez had suggested that head coach Michael Carrick had been let down by a lack of summer signings. On Thursday, Martínez met with United's hierarchy at the club's training ground before releasing a statement on social media acknowledging that his frustration led him to speak at the wrong time and place.
