No, Erik just swings his right foot at the ball occasionally and hopes for the best, he has no control or confidence in it at all, and the results are highly erratic. He'll generally goes to great lengths to avoid using it and it stifles his and our play. I don't know how anyone could claim anything differently after watching him a prolonged length of time.
I don't have six years worth of experience watching Jack Clarke but my early vibe is that being one footed won't be an issue but weather he could get to Son, Eriksen or Kane levels of weaker foot ability, only time will tell.
