I'd add that a midfielder needs to pitch in with a goal or 2 - Rico gets into so many great positions but his finishing has to be one of the worst in the club.How is he a midfielder?
Traits of a midfielder are ball playing and being able to get around the pitch, or be able to control the midfield with passing ability
Then an ability to help defend and to score or create goals
Lewis does none of the above, and has been upgraded because he came through the academy
He's an absolutely average footballer who excels at nothing
