I'd say we're missing both profiles if we're to continue with a midfield two. Caqueret is someone who I would say is best utilised as the secondary #6, next to a defensively strong player like Tchouameni, who would provide a foundation for players like Caqueret to progress play. While Tchouameni potentially dominates zones in defensive transition by winning aerial balls, defending space in a high block against the quickest of attackers, as well as providing support in possession. These attributes aren't valued by many fans but it's necessary to have such players which creates a defensive balance/platform in defensive transitions for the team's ball players.
We have a number of players coming through the ranks with a similar profile to Caqueret, but there's not many with the profile of Tchouameni, as far as the qualities he brings in a low/mid, and high blocks, which could potentially allow us to utilise a 3 man midfield with two #8s. A midfield 3 of Tchouameni, Caqueret and Hannibal could potentially work.
