Yip. Wide players is one area where we do actually have a number of top quality players, Forrest, Fraser, Snodgrass, Ritchie, Phillips, even Burke in the U21s. Yet he’s dropped them all just so he can shoehorn Tierney into a 3 man central defence, a position he doesn’t even play in regularly! And that means that Robertson is playing wing back, again, a position he doesn’t normally play! As you say, play Tierney at right back. Most wingers cut inside these days anyway. It will suit him!
