Arsenal forward Joel Campbell says he deserves more playing time at Emirates

But after starting none of Arsenal's last 10 games in 2015-16, and only playing a bit-part in pre-season, he has again been overlooked by Wenger.

And much to the player's disappointment, he's not been given the chance to prove himself at the Emirates this term.

"I am at an important step in my career," said Campbell. "[But] there would not have been many chances to play at Arsenal.

"I could have chosen to stay, to have a good salary.

"I think I deserved to play more after what I did last year, but now this is a new stage.

"I want to continue to develop. Sporting are a good opportunity for me and a great team. I am happy with the decision I made."
