the championship is a very high level from middle table to the top and not much from the bottom of the premier league celtic are so over rated with them winning everything in scotland from leagues and cups i don't think that squad they had last season would be anywhere near in the premier league and weak and bottom 5 clubs at best
yes celtic would do well after about 4 or 5 seasons but again the top 6 clubs in england would still be way ahead of them and there fans would be fighting each week when getting dicked by the likes of stoke and newcastle so they would end up being kicked out
anyway back to roberts ask yourself sterling sane jesus silva all at a very young age and done it at the highest level last season and your saying roberts could take a shirt of any of them hahahhahahahahaha
