Carrick: 'No concerns' over Martínez's Utd commitment

Manchester United interim manager Michael Carrick has dismissed concerns about Lisandro Martínez's commitment to the club, stating 'I've got no concerns about commitment at all.' The 28-year-old Argentine defender was sent off at Stamford Bridge after conceding a penalty in a 2-0 loss to Chelsea, and had previously criticised director of football Jason Wilcox following a 2-0 defeat to Atlético Madrid. Martínez, who is out of contract at the end of the season, was also at fault for Tottenham's late equaliser in a 1-1 draw at Old Trafford last month.
