I smell desperation tbh. Yes, I believe he'd be useful to us, he's calm on the ball and distributes it better than all our mids except Locatelli. However, if we really want this kind of profile, why not take back Rovella? I'd let Roma have Arthur as long as they take over his full salary.
Not complaining here but it's kinda weird. Maybe we don't want to interrupt Rovella's loan - that I understand, makes sense. He's a starter there, playing 90 minutes every week is important to him.
