Just back. Looked like a change in formation to me, with a diamond in midfield allowing full backs to push up. Downes as the holding midfielder and Alcarez at the point as a false 9. With two up front in Armstrong and Sulemana. Team looked much better connected, without the huge gaps as in recent games. And they were mixing it up, going long sometimes. Defended well second half. Think that he might have stumbled on a formation that actually works.
