The next option is to play a wider player on one wing. In the above formation, it shows Shinji Kagawa or Ashley Young taking up a wider role on the left, but it could as easily be Antonio Valencia taking up a wider role on the right in what would be a mirror image of the above formation.
This will provide a bit of width on at least one wing while the full back can push up on the other wing to provide width. This will obviously make it easier for the midfielders to cover the fullback if only one of them is pushing up at one time.
