I'm sorry, have you seen his tackling? Instant yellow cards against sweden and sampdoria
And his non-tackling led to a goal against Atalanta
And his attempted clearance yesterday...
And you want him to be a BTB
His best position is CAM , he has a good touch and pass and can beat his man...just needs to do it more consistently and link up better which I guess will come with time, but at this moment he isn't fully ready
