He played 36 of 38 games in the league last season. Clearly he's first choice.Although i dont actively want any one of our first teamers to leave i could accept walker and dier if it was daft money. Every player has an amount you can't say no to.
Dier is in all honesty not first choice in any position he plays even though he is important for us.
Selling a player for an acceptable amount, doesnt necessarily make us a selling club
