The 21-year-old winger has become Bolton manager Gary Megson’s fifth signing of the summer.
Megson told the club’s official website. “Lee is another good addition to our squad. He has got pace and ability. It is great that we have finally been able to get him.
“It is going to be a big challenge for him because he is coming to a new country and a new culture, where he will be facing the demands of the Premier League.
“It will take time for him to settle, but we will be making sure that he is fully supported as he makes that transition.”
