Arsenal transfer news and rumours: Manchester City ready to give in to Alexis Sanchez's wage demands?
“Alexis Sanchez is a big shadow hanging over the Emirates,” Smith told Talksport.
“Arsene Wenger says he is determined not to sell him, but he seems determined to leave.
“If you’ve got an unhappy player, a bit like Coutinho at Liverpool, that’s not a great situation to have in the dressing room.
“For me, it’s a no-brainer: you’ve got to let him go, get the money and move on."
