Dean Smith claims Manchester United's match-winning penalty against his Aston Villa side should not have been given in the Midlands club's 2-1 loss at Old Trafford.
Villa were drawing 1-1 after Bertrand Traore's goal early in the second-half cancelled out Anthony Martial's opener when Paul Pogba went down in the area under a challenge by midfielder Douglas Luiz.
Michael Oliver awarded a penalty which Bruno Fernandes converted in United's win and while Smith thought it was a penalty in real time - the Villa boss thinks Pogba tripped himself up after looking at a replay.
