I think he will be more of a classic CM and not necessarily a B2B in the Vidal/Barella sense of the role, Locatelli is not that great as a full time box to box and neither as a full time regista but is however good enough at both and can always play as a LCM/RCM that at times also drops deeper to take pressure off Paredes and start moves, also from the same classic left CM or right CM role he can be more involved in the final third overall by not always being so deep and gives him a bit of a free roam to also get more in the opposition box as a B2B type but overall to be involved essentially everywhere, which is what he is good at, not great at something specific but quite well rounded and decently good in every midfield role, rather dynamic in a sense, very usefull and efficient in terms of defensive cover too for when fullbacks or other CM’s are caught further up the pitch.
