He's been posting Instagram stories from a gym in Italy the past few days. The one today had him wearing a TFC uniform while working out though. So he probably doesn't hate the team or anything, which is good
I'm 99% sure he is retiring. The gym he posts from (Healthy Form Genova) he seems to either own or have some partial ownership in.
I can't see him signing for any club in SerieA just to ride the bench for a year.
