Carrick 'baffled' by inconsistent penalty calls as Man Utd held
United took the lead from the spot through Bruno Fernandes but were denied a second penalty when Amad Diallo went down inside the box under a challenge from Adrien Truffert.
Bournemouth immediately broke to equalise when Truffert teed up Ryan Christie to level.
A James Hill own goal restored United's lead before Harry Maguire was sent-off and conceded a penalty for bringing down Evanilson.
The contact on the Brazilian striker was remarkably similar to that ignored by the officials for Truffert's challenge on Diallo.
