He reminds me of Alaba. Similar face and versatility (full back, midfield and centre back). Alaba was originally a midfield and converted as a left back at Bayern but since Guardiola came, Alaba has been playing first team in left back, midfield and centre back. I can see a similarity between Alaba and Mensah. Mensah is just natural brain talent for a footballer and with additional of physical and technical gift he has, he will be a top player. I don't think midfield is his #1 position as I think his passing is still not good enough for top team level but that doesn't mean he can't improve that aspect so he might can prove me wrong for this one. Right back and centre back he looked very good and ironic that we actually need right back, centre back and another centre mid as well. I can see Mensah will be used as a first team starting eleven anytime soon but playing everywhere like Alaba.
