Its not though. I know you think it is too attacking but a front 3 of Jesus, Mbappe, and Sanchez and a midfield four of Sane, Sterling, Carvalho, and Silva is a real possibility under Pep. Add to that, I think Pep's statement that he didn't play them as wingbacks is semantics. If he played a back three with no fullbacks and did play two wingers; they by definition would play as wingbacks even if they were called wingers. Sane was constantly coming back to defend against Everton in October.
