Daley Blind says Manchester United need to stand up and prove their worth after being caught cold by Fenerbahce.
A topsy-turvy start to the season continued in Turkey, where United wilted on a hostile night at the Sukru Saracoglu Stadium.
Moussa Sow's exceptional overhead kick after 65 seconds was a sucker-punch and infuriated manager Jose Mourinho, who accused his players of approaching the match like a 'summer friendly'.
Jeremain Lens' excellent second-half free-kick compounded matters, with Wayne Rooney's superb late goal and a frantic ending unable to mask a poor United display in Istanbul.
