West Ham boss Zola: Stoke move good for Etherington
Etherington came off the bench in last weekend's FA Cup win against Barnsley but has not featured in the league for West Ham since mid-November.
Zola said: "We chose to do the best for all parties involved. It is good for him. He will be playing regularly. We left on very good terms. We wish him all the best. He is a player we want to do well."
