"It is obviously very scary to move away from my family but it is my dream to play in England and what I have always wanted to do so that outweighs any apprehension I had about moving here.
"Playing for the Under-21s has been the best experience for me and I am so grateful to the coach for giving me that opportunity as it has helped me develop my game so much quicker. I am sure that is part of the reason West Ham signed me."
