The Red Devils have struggled this season and sit fifth in the Premier League, with the striker arguing that they have lost their old aura of invincibility.
Stoke City striker Peter Odemwingie has claimed ahead of his side's visit to Old Trafford that Manchester United has lost the fear factor that used to terrify teams.
Red Devils boss Louis van Gaal has come under increasing pressure this season after a number of lacklustre performances from his players and a group-stage elimination from the Champions League.
The club sits fifth in the Premier League - 10 points behind table-topping Leicester City - and Odemwingie claims United has lost its previous aura of invincibility.
