I don't mind with those terms or anything but holding is not Bakayoko strength. Different atributes, and the comparison is tiresome, but Bakayoko's role is similar to Fellaini in midfield 2 or midfield 3. Yes he does defensive work, but not that impressive in a role of holding, calmer influence, but robust, stiffle opposition midfielder. He was tried as holding mf at times, but more meh than yay. He may work with midfield of Herrera & Pogba like Fellaini, but may not bring the team to the next step. This point is personal take, of course.
