Apart from starting heavy courses in Italian, I don't expect or want Ramsey to be doing anything else connected with Juventus this season. Arsenal might be shite, but are a club that has given a lot to him and any decent person would repay that trust. Daydreaming is not normal for 10 mil a year professional players.
If he was already thinking all about Juve we wouldn't sign him, I suppose. That's what scouting off the field is all about.
