I'm not making a direct comparison. They're of course different types of players. The whole argument on this thread has been whether he justifies the hype. It is not whether he can become world class or not. My point has always been that he is not showing enough to gather such hype, to be a potential good player, yes but not the standards that is been branded about. At 18, Pearson showed mode than one attribute, albeit not refined which is more than what Sanches is currently known for.
I have watched Sanches at least 10 to 12 times this season and this has been the basis of my arguments. Not YouTube or highlights. I took an interest in Benfica this season to watch Goncalo Guedes, another Benfica player that was hyped in epic proportions. I almost fell for it too especially after the sale of Markovic to Liverpool. It was in that period till that I noticed Sanches, and my conclusion is that what he is good at, energy and drive, he is awesome but overall, he is nowhere near the level of 18 year old CMs that are in the world class bracket.
