Jol has been impressed after testing Bale as a midfielder, and he believes the 18-year-old is learning the responsibilities of being a defender after he was given a chance at left-back against Middlesbrough last week and scored again, his third in three starts.
"That was the first time that he played left-back so there will be a lot of progress," Jol said. "But he did well, just 18, scored three goals, made an impact against Boro and before. That is why we bought him."
