Not only that, I think he can also be utilised as a inverted RB. He would provide tactical flexibility by potentially being a option in three positions. And that is a dream for a head coach like ten Hag who like other positional play coaches want players who can slot into different roles.
And if United had the money to sign two midfielders, along with a creative CM like Frenkie de Jong. Then one of Caicedo or Rice would be a good option alongside a more creative CM, and I'd sell one of the right backs to integrate one of the two players into the team.
And that would also potentially provide a solid foundation to integrate some of the younger midfielders into the team. And we'd have a midfield of Casemiro, de Jong and Bruno as the AM, with either Caicedo or Rice inverting, and we'd also have a DM ready to take over from Casemiro if he's not available.
