Opinions on Renato Sanches?

Hi guys, I'm a Man United fan. Have been seeing us linked to Renato Sanches a lot in the last couple of weeks, so I watched a few Youtube highlight videos and managed to catch the Zenit match last week. Looks like you have a really exciting player on your hands. Of course, a few videos and one match don't tell a whole story, so I was hoping to get some insight from you guys.

Since the people in this sub are proper Portuguese football fans and watch their team play every week, I'm interested to know anything you can tell me about Renato's playing style, his strengths/weaknesses, how he is viewed in Portugal, how good people believe he can be, etc. Also, do people in Portugal seem to think he is going to stay at Benfica another few seasons or leave for a different league?

Thanks

Edit: Also, while I'm here - can anyone fill me in on how Bebé is doing?
