QPR chief executive Phil Beard labelled Ashley Young a diver after he won the penalty that resulted in Manchester United's opening goal in a 2-0 victory for the title chasers at Old Trafford.
Young appeared to go down easily under pressure from Shaun Derry, who was shown a straight red card before Wayne Rooney tucked in the first-half spot-kick. Beard then likened Young to British Olympic diver Tom Daley in a Twitter post that was re-tweeted by QPR majority shareholder Tony Fernandes.
"Difficult to take after watching numerous replays but Ashley Young could partner Tom Daley at the Olympics #QPR," he wrote. QPR boss Mark Hughes said the club will appeal against Derry's dismissal.
QPR director Ruben Emir Gnanalingam was also aggrieved, pointing to the fact Young also appeared to be offside in the lead-up to the incident, adding: "It was offside and a dive by Young! Alex Ferguson's luck with calls continues. Just wish there was video technology!"
Fernandes replied to that tweet, saying: "Awful. Spoilt another game." He then added: "Thank you to all the manchester united (sic) fans for their honesty. Have received 150 tweets saying he was offside and was never a penalty."
Midfielder Derry is set to miss Wednesday's encounter with Swansea at Loftus Road, but Hughes confirmed the club will challenge the red card.
"Yes. We will appeal the red card," said Hughes.
"We need all hands on deck on Wednesday, plus Shaun has had a rest. He only played for 15 minutes."
