“Even though Pierre-Emerick left Dortmund for Arsenal , we remained in contact. I have spoken with him on and off ever since he moved here.
“I asked him how it was in London and stuff. He loves it here. He is a big city kind of guy, you can see that and he has told me about a few places to go see.
"It was a very good friendship when we played for Dortmund together for a few years. He was there when I first broke into the first team and we had a nice link up on the field.
“He taught me a lot. That was one of the coolest things about him. He's a very humble guy and perhaps people don't know that about him."
