The Turin Sports reported that Lukaku was injured in a friendly match in Naples.

Naples' friendly match with Olympiacos is in progress, which is the last warm-up match before the new season. However, in the 32nd minute of the game, Lukaku landed his left foot unsteadily while fighting with his opponent, and then injured after completing the shot with the same foot at the penalty area line. The striker had problems with his left thigh muscles, and the team doctor immediately gave him ice to treat his muscles. The Belgian was obviously limping when he left the field and gestured to the coaching staff to show his muscle injury.

In addition to Lukaku's injury, Conte also lost control of his emotions during the game. As the on-field confrontation escalated (the player of Olympiacos pedaled on Rachmani's bright soles in the 35th minute), the angry Conte rushed out of the technical zone to confront the opponent's players, fiercely protesting such dangerous moves in the friendly match. A brief chaos occurred on the scene, and eventually the team manager Paul Rea pulled Contira from the conflict zone.
