Agree that De Paul probably doesn't have a great fit at Conte's football. Maybe if he's pure rotation option for Sensi's current role. But loan deal would be ideal, to test how he pans out under Conte. If he pans out, why not? We should aim for level where we have 25-30m€ bench players.
Good thing is he's not a midget (this is no offense to short persons, I'm a short person myself) and of course the basic abilities for playing the ball in his feet unlike Vecino and Gags.
