Hope not. Hate wingback systems. If you're gonna go 3 at the back go about it properly and play wingers. Also don't think 1 holder with a back 3 is ideal for the buildup
Rather go back to a more rotational back 3/4 hybrid
Alaba would be the most ideal LB for us, as he, like Walker on the other side, is adept at overlapping the winger, playing CB and moving into DM. Ake can probably do all of those bar overlapping the winger (one reason why losing Sane is such a blow imo) but if Foden, being left footed, was allowed to play the leftsided AM position he could do some of that.
eg.
Sterling -- Aguero ----Torres
-- Foden --- De Bruyne
--[Ake]- Thiago (Walker)
---(Ake) Laporte Koulibaly [Walker]
Ederson
When Walker is in the back 3 Ake moves to DM and vice versa (all depends on which side of the pitch the ball is on)
One can dream
