Hall, a winger, is excited to be playing with the England striker.
He told West Ham TV: "We have definitely brought top players in. Yossi has come back and I was really young the last time he was here so it is nice to see him about.
"It is also great to have Andy coming in. He is a very big striker and I hope he and Carlton do well. I am obviously small so I think I can work well playing off them. Playing and training with them will only help me to develop my game."
