So you say we only have two traditional wingers, one who thanks to AVB isn't a winger and Lennon who has come inside much more this season.
Your post hasn't done anything to suggest AVB likes his wingers to hug the touchline and cross the ball in?
to who? a huge part of the myth of Lennon's "poor final ball" has been we have nobody that gets on the end of it.
Lennon is still very much a winger that plays wide (see how we have no width when he doesn't play), he come in at the end and now attacks the far post a little more because it makes him more of a goal threat. Again Bale plays in because that's what has allowed him to score 20+ goals in a season where we desperately needed someone to help score.
It's all speculation, but imo under AVB the ideal team still is Bale - Sandro - Dembele -Lennon, which is using the width.
