Swansea boss Paul Clement accused Manchester United's Marcus Rashford of having 'deceived' referee Neil Swarbrick to win a penalty in the 1-1 draw between the sides at Old Trafford.
Swarbrick awarded the spot-kick, which was converted by Wayne Rooney to put United ahead, after Rashford went down in the box in first-half stoppage time as Lukasz Fabianski dived at his feet.
Replays indicated Rashford was already on his way to the ground before there was contact between him and Fabianski.
When asked about the incident after the game, Clement said: "Replays show the player deceived the referee - there is no other way to look at it.
