I think Newcastle could benefit with a good natural winger though our strength lays in the amount of players who can chip in on the wings.
Gutierrez is a great attacking player but his strengths lay in the fact that he's a good defender as well. He only has 3 goals and 4 assists this season, though he can make shit happen.
Ben Arfa is more of a natural winger and has been somewhat potent in 21 appearances, with 4 goals and 3 assists. For his first full season in the league, it's not bad given many were short sub appearances. He can still improve a lot more though. Next season I will expect a fair bit from him.
Ryan Taylor has 3 goals and 6 assists.
Obertan has 1 goal and 6 assists.
Those 4 players have provided half of our goals for the season.
