Think his problem is that all the shots vs Inter have been at mid height. You either go low, or high. You have much more control if you go low. Mid distance is the easiest reachable position for a keeper. You need to be mega precise to score at mid height if the keeper expects it. Like his goal.
Think this is an area that his flamboyance is hurting him. Messi learned very fast in his career that low shots are golden. Lamine has the Neymar sickness of thinking a high shot brings more flair. They don't, they just limit you.
I think he should look for the low shot more. When you want to be a scorer, volume counts, not the aesthetic merits of a goal. If you aim to score golazos, you'll end up a 10-15 goals a season player. Nobody scores 40 goals while constantly aiming for the top corners. Start mixing it up, he almost never shoots on ground level. Almost always goals for the most difficult shots.
