The brother of Manchester United assistant manager Ryan Giggs has tweeted a message that appears to take aim at Louis van Gaal.
The Dutchman's position at Old Trafford looks increasingly uncertain after his side went down 2-0 at Stoke City for their fourth consecutive defeat in all competitions.
Taking to Twitter after the game, Rhodri Giggs posted: "Mourinho to his driver 'start the car'".
Former Chelsea boss Jose Mourinho is the current 8/13 favourite to replace Van Gaal in Manchester, while a promotion for Giggs is thought to be the second most likely option, with odds of 2/1.
