Lisandro Martinez has returned to Manchester United training after apologising for his criticism of the club’s management, according to The Sun.

The defender held talks on Thursday with head coach Michael Carrick, sporting director Jason Wilcox and chief executive Omar Berrada. The club considers the matter resolved, the report says.

Martinez’s comments followed Manchester United’s 2-0 defeat by Atletico in the Champions League, after which he criticised the club’s work in the transfer market. The Argentina international later apologised for his remarks.

Martinez has made seven appearances for Manchester United in all competitions this season and has scored one goal.
