So many knee-jerk reactions to this loan deal, with nobody knowing what anyones thinking.
I can absolutely understand why Patrick went back to Celtic, he's only 20, he'll be playing football regularly with players he likes and linked up with well, he has a good relationship with the manager, and the fans love him more than they really should for a loanee (it's almost stalkerish).
He could be thinking, why go on loan to another foreign club, what if he doesn't mesh with the players (doesn't know the language), or the manager, what if he doesn't get to play the way he wants, and what if he detests it and football at only 20 years of age. Everyone is thinking about Patrick's future at City, but Patrick is thinking about his football future in general (possibly isn't at city), in that sense, another year at Celtic is sensible and I might be tempted to do the same.
