When he does the hard work and gets into these areas he needs to do more with the ball. If he is surrounded then try to win a corner, a penalty, anything that contributes. A few times again he ended up stood 1v1 or 1v2 against defenders and tried to dribble through but with no effect. Be smarter and take the pressure off the team, his acceleration and cross are both very good so he just needs to make better decisions.
