Former Roma chief Walter Sabatini has taken aim at Romelu Lukaku.
Lukaku joined Roma last week on-loan from Chelsea.
"All that happened with Lukaku was just unpleasant," Sabatini, referring to his departure from Inter Milan, told TV Play.
Directors need to follow ethical principles and players ought to as well. This was a club that showed faith in him, made him happy with Antonio Conte, then protected him when he was playing really badly last season.
Inter always had a faultless attitude with him. His attempt to run away scandalised me, it's quite simply a matter of ethics."
