Man Utd can make three January signings to immediately address Lisandro Martinez complaint

Manchester United could use the January transfer window to prove their ambition after Lisandro Martinez accused the club's hierarchy of failing to invest in the playing squad. The defender went on an extraordinary rant following Tuesday's defeat to Atletico Madrid , pointing the finger at senior figures including director of football Jason Wilcox. As a result, his future at Old Trafford is believed to be uncertain , with his contract already set to expire at the end of the campaign.
