Did Anthony Martial become a new victim of coach Jose Mourinho?
The 20-year-old Frenchman caused a stir when he unexpectedly decided to stop following "Man Utd" club's social accounts on both Twitter and Facebook.
Other internet users speculate that the striker is sad about losing his shirt number - the number 9 jersey will now be worn by Zlatan Ibrahimović.
Let's remind that Martial moved to Manchester from Monaco a year ago, with a transfer fee of £36 million. This sum could increase to £58 million in the future.
During the last season, the player scored 11 goals in 31 Premier League matches.
