I agree, young, new to the club and league, arriving late for preseason. Let's be patient and see how things turn out for those first couple of months.
Most likely sub appearances and cup games at first. If he makes a quick impact he may get some starts in the league, where and in which formation will depend on what the team needs and his performances up to that point.
Medium to long term I think it's difficult to predict where he ends up playing. Personally I'd guess the right, but impossible to know right now.
