Seems pretty out of order to me and a way of trying to get more pressure heaped onto the player who's still trying to get his confidence back after that whole 'song' debacle.
No, the song "debacle" had nothing to do with his dip in form. That's absurd, agenda-driven nonsense.
The Lukaku song started on
September 13th against Basel (bagged a goal).
Sep 17: Everton: goal
Sep 23: Southampton: goal
Sep 27: CSKA: 2 goals
Sep 30: Crystal Palace: goal
His slump started 2 weeks after that, against Liverpool October 14th, and finally broke November 18th against Newcastle when -- guess who -- Pogba returned.
His drop in confidence coincided with being unable to permanently put to bed the narrative that he can't score against big clubs. It had
nothing to do with the song, which he never said he was offended by.
