Dean Smith hit out at the 'pathetic decision' to award Manchester United a penalty for Douglas Luiz's challenge on Paul Pogba at Villa Park on Sunday.
The same two players were involved in an incident that led to Bruno Fernandes scoring United's winner from the spot at Old Trafford in January.
Fernandes also converted a penalty at Villa Park last season when he was fouled by Ezri Konsa.
Former referee Mark Clattenburg: My verdict
Come off it Dean, it's a clear penalty!
