Are you actually going to discuss Doherty is it only going to be about me?
Our RB slot:
Walker>Doherty-Aurier>KWP>Tripps>(Sissoko)>(Foyth, Tanganaga, Toby, Sanchez)>(Gedson).
I don't see Doherty as an upgrade on Aurier there are +/- to each, some nuanced given their roles asked of them by their managers but I see Doherty better offensively and Aurier better defensively but on balance I see them as broadly similar in their standing. Because of this, I would be more than happy to see them both play for Spurs next season and compete for this spot.
However, if we sell Aurier I absolutely do not see us having made any improvement in this position whatsoever. I do not see from our current squad who is capable enough at providing quality cover if we don't bring in another RB (if selling Aurier). I think it's a big risk to have a soon to be 29yr old in this position without quality cover.
