Depends what you term a £30m player tbh. A fair amount of worse players, with less potential than O'Riley have changed hands for that sort of money by clubs in the premier league, players who you could barely class as a regular professional footballer as yet, the boy Anderson at Newcastle being one example of many. And for the CL, for context, he was awarded UEFA MOTM in 2 of the 6 games last season, looking beyond the stats he had an excellent campaign for us and was a shining light, hence Atletico's interest in him off the back of coming up against him 6 months ago.
