Rangers fan here, not read the full thread but on this page it seems everyone isn't convinced of him.
I mean this with the greatest respect but he will end up at better side than yourselfs in the future. I know the standard is way below what he's up against in the epl. Most of our league is probably bottom end championship so I don't get carried away to much when players look good against them. However, he came into a very good rangers side and didn't look out of place one bit, he started against lyon away in a 2-2 draw in Europe and it was if he was having a kick about down the park with his mates. For his age the composure he showed you would have thought he was a seasoned pro.
I actually think we should have sold tav (our captain) to accommodate patterson and kept him for a few years before he moved on to a better league. He is still learning so there will be mistakes at times, the problem now is he's in a league where if you make a mistake he's playing against real quality that hel get punished for it, also in the epl very few teams of being able to carry someone through games while they learn. Up here mistakes aren't punished nowhere near as much so mistakes made by players get papered over a bit.
When KT left celtic for arsenal a few up here said hel get found out down there, I always said hel hold his own down there, IMHO patterson will go on to be better than him.
