He has never been a center forward but we are asking him to play that way because it suits the system.
His best time with us was playing on the left as an inside forward. Even during his best spells his goals came from moments if individual creativity, benefiting from the extra time and space you get playing out wide.
He's not going to hold up the ball, he's not going to win aerial duels, he's not going to play in small strikers or attaching midfielders. In short we are not playing to his strengths, we are using him because we have no strikers that actually fit the system.
