I've never understood the shouts to move him into midfield when he is one of the best in the world in his current position and is vital to how we play.
And it'll still come up by LFC fans or pundits every while and so.
My understanding is a bit like when Pep tried putting Lahm in midfield: you can do it, sure, but you lose one of the best in the world at his original position. The space Trent gets as a RB/almost RWB is always gonna be way bigger than at midfield, and his whipped crosses would suffer from it. Beckham put in lots of crosses, but, if I remember correctly, at the very end of a very classic 4-4-2, which no one plays these days.
Neco seems quite good, but there's no reason why the two can't be rotated there. Real Madrid has won lots the past years having Carvajal as a main, with Nacho, academy graduate, covering when needed. Nacho, at least, doesn't need to be a full blown starter, and that's a thing with big teams that win lots of things (which is where we finally are, again): not every talent has to be a starter, as long as they understand they're playing consistently for big trophies.
