He's an AM playing LM in a defensive role, by your logic, if Utd buy Sanchez they should be able to play him LB and still expect him to be their best player. Our problem is we already have too many players out of position and it's all down our left side, the team has no balance. You can't expect a player to be able to operate as a playmaker from a defensive position in a poor team, that's why it's not working.
But he hasn't always played from a defensive position for us, he has played the majority of his games for us in an attacking role, whether in the middle, or coming in from the left, and it's all about opinions, but I'm still yet to see this 'top quality' player.
