Lisandro Martinez branded Man United 'bluffer' after claims defender 'threw in the towel'

Manchester United defender Lisandro Martinez has been labelled as a 'bluffer' in a rant by former United man Nicky Butt . Martinez had a day to forget on Saturday as he was shown a red card for an elbow after conceding a penalty in the 2-0 away defeat vs Chelsea . The loss leaves Michael Carrick 's side winless in their last nine games in all competitions, having lost their last three by an aggregate score of 9-1.
