I actually think he would do alright if we'd bring him back next season. Nothing extraordinary, but kind of like Giovinco did this year.
However, if we aren't completely unlucky and something like Immobiles Genoa season happens, another year out on loan would be much better for his development, and seeing as we don't really need him from a competitive sense nexts season, I'd rather wait another year to then have a better, more finished player.
