banduan -- they're both playing quite a bit this season:

Tchouameni is the regular starter as the deepest CM in a four man midfield. Camivinga has played at LB (working into midfield) and also at CM.
Both playing well and central to the team, not sure either leaves unless Real Madrid signs a class CF and reverts to a 4-3-3. Even then, Camavinga could play as a 6, 8 or LB so unlikely he moves along, while Tchouameni would likely be the starting DM (if they rolled with a single pivot).
