Juan Mata jokingly took aim at his Manchester United teammate Nemanja Matic by suggesting that the Serb isn't keeping up with his training regime at home.
Due to the global coronavirus pandemic football in England and across the world has ground to a halt, with the Premier League suspended until at least April 30 and UEFA suspending all competitions 'until further notice' on Wednesday.
As a result of government rules which say people should only leave the house for essential journeys in order to combat the outbreak, United's Carrington training ground is closed.
Instead, United's stars have been given personalised training regimes to do while at home in order to keep fit for when the season resumes.
