Cunha scored twice inside four minutes to complete a dramatic turnaround at Old Trafford – but then got sent offGettyHowever, the Brazil forward was sent off in the dying moments as United clung onto their first win in ten matches. Having already been booked for taking his shirt off, Cunha was shown a second yellow for a late challenge moments after the 86th-minute winner. The 27-year-old did not get very far down the tunnel and quickly re-emerged to join in the post-match celebrations after the full-time whistle.
